MAXIMAL $L^1$-REGULARITY OF GENERATORS FOR BOUNDED ANALYTIC SEMIGROUPS IN BANACH SPACES Myong-Hwan RI, Reinhard FARWIG 数学物理学报(英文版). 2022 (4):  1261-1272.  DOI: 10.1007/s10473-022-0401-8 摘要 ( 145 )   RICH HTML PDF   收藏 In this paper, we prove that the generator of any bounded analytic semigroup in $(\theta,1)$-type real interpolation of its domain and underlying Banach space has maximal $L^1$-regularity, using a duality argument combined with the result of maximal continuous regularity. As an application, we consider maximal $L^1$-regularity of the Dirichlet-Laplacian and the Stokes operator in inhomogeneous $B^s_{q,1}$-type Besov spaces on domains of $\mathbb R^n$, $n\geq 2$. 参考文献 | 相关文章 | 计量指标

$\mathcal{O}(t^{-\beta})$-SYNCHRONIZATION AND ASYMPTOTIC SYNCHRONIZATION OF DELAYED FRACTIONAL ORDER NEURAL NETWORKS Anbalagan PRATAP, Ramachandran RAJA, 曹进德, 黃创霞, Chuangxia HUANG, Ovidiu BAGDASAR 数学物理学报(英文版). 2022 (4):  1273-1292.  DOI: 10.1007/s10473-022-0402-7 摘要 ( 63 )   RICH HTML PDF   收藏 This article explores the $\mathcal{O}(t^{-\beta})$ synchronization and asymptotic synchronization for fractional order BAM neural networks (FBAMNNs) with discrete delays, distributed delays and non-identical perturbations. By designing a state feedback control law and a new kind of fractional order Lyapunov functional, a new set of algebraic sufficient conditions are derived to guarantee the $\mathcal{O}(t^{-\beta})$ Synchronization and asymptotic synchronization of the considered FBAMNNs model; this can easily be evaluated without using a MATLAB LMI control toolbox. Finally, two numerical examples, along with the simulation results, illustrate the correctness and viability of the exhibited synchronization results. 参考文献 | 相关文章 | 计量指标

GLOBAL WELL-POSEDNESS OF THE 2D BOUSSINESQ EQUATIONS WITH PARTIAL DISSIPATION 晋雪婷, 肖跃龙, 于幻 数学物理学报(英文版). 2022 (4):  1293-1309.  DOI: 10.1007/s10473-022-0403-6 摘要 ( 74 )   RICH HTML PDF   收藏 In this paper, we prove the global well-posedness of the 2D Boussinesq equations with three kinds of partial dissipation; among these the initial data $(u_0,\theta_0)$ is required such that its own and the derivative of one of its directions $(x,y)$ are assumed to be $L^2(\mathbb R^2)$. Our results only need the lower regularity of the initial data, which ensures the uniqueness of the solutions. 参考文献 | 相关文章 | 计量指标

WEIGHTED NORM INEQUALITIES FOR COMMUTATORS OF THE KATO SQUARE ROOT OF SECOND ORDER ELLIPTIC OPERATORS ON $\mathbb R^n$ 陈艳萍, 丁勇, 朱凯 数学物理学报(英文版). 2022 (4):  1310-1332.  DOI: 10.1007/s10473-022-0404-5 摘要 ( 120 )   RICH HTML PDF   收藏 Let $L=-\mathrm{div}(A\nabla)$ be a second order divergence form elliptic operator with bounded measurable coefficients in ${\Bbb R}^n$. We establish weighted $L^p$ norm inequalities for commutators generated by $\sqrt{L}$ and Lipschitz functions, where the range of $p$ is different from $(1,\infty)$, and we isolate the right class of weights introduced by Auscher and Martell. In this work, we use good-$\lambda$ inequality with two parameters through the weighted boundedness of Riesz transforms $\nabla L^{-1/2}$. Our result recovers, in some sense, a previous result of Hofmann. 参考文献 | 相关文章 | 计量指标

ITERATIVE ALGORITHMS FOR SYSTEM OF VARIATIONAL INCLUSIONS IN HADAMARD MANIFOLDS Qamrul Hasan ANSARI, Feeroz BABU, D. R. SAHU 数学物理学报(英文版). 2022 (4):  1333-1356.  DOI: 10.1007/s10473-022-0405-4 摘要 ( 54 )   RICH HTML PDF   收藏 In this paper, we consider system of variational inclusions and its several spacial cases, namely, alternating point problems, system of variational inequalities, etc., in the setting of Hadamard manifolds. We propose an iterative algorithm for solving system of variational inclusions and study its convergence analysis. Several special cases of the proposed algorithm and convergence result are also presented. We present application to constraints minimization problems for bifunctions in the setting of Hadamard manifolds. At the end, we illustrate proposed algorithms and convergence analysis by a numerical example. The algorithms and convergence results of this paper either improve or extend known algorithms and convergence results from linear structure to Hadamard manifolds. 参考文献 | 相关文章 | 计量指标

THE GENERALIZED HYPERSTABILITY OF GENERAL LINEAR EQUATION IN QUASI-2-BANACH SPACE Ravinder Kumar SHARMA, Sumit CHANDOK 数学物理学报(英文版). 2022 (4):  1357-1372.  DOI: 10.1007/s10473-022-0406-3 摘要 ( 50 )   RICH HTML PDF   收藏 In this paper, we study the hyperstability for the general linear equation $$f(ax+by)=Af(x)+Bf(y)$$ in the setting of complete quasi-2-Banach spaces. We first extend the main fixed point result of Brzdȩk and Ciepliński (Acta Mathematica Scientia, 2018, ${\bf 38B}$(2): 377-390) to quasi-2-Banach spaces by defining an equivalent quasi-2-Banach space. Then we use this result to generalize the main results on the hyperstability for the general linear equation in quasi-2-Banach spaces. Our results improve and generalize many results of literature. 参考文献 | 相关文章 | 计量指标

NO-ARBITRAGE SYMMETRIES Iván DEGANO, Sebastián FERRANDO, Alfredo GONZÁLEZ 数学物理学报(英文版). 2022 (4):  1373-1402.  DOI: 10.1007/s10473-022-0407-2 摘要 ( 43 )   RICH HTML PDF   收藏 The no-arbitrage property is widely accepted to be a centerpiece of modern financial mathematics and could be considered to be a financial law applicable to a large class of (idealized) markets. This paper addresses the following basic question: can one characterize the class of transformations that leave the law of no-arbitrage invariant? We provide a geometric formalization of this question in a non probabilistic setting of discrete time-the so-called trajectorial models. The paper then characterizes, in a local sense, the no-arbitrage symmetries and illustrates their meaning with a detailed example. Our context makes the result available to the stochastic setting as a special case. 参考文献 | 相关文章 | 计量指标

THE EXISTENCE AND BLOW-UP OF THE RADIAL SOLUTIONS OF A ${(k_{1},k_{2})}$-HESSIAN SYSTEM INVOLVING A NONLINEAR OPERATOR AND GRADIENT 王国涛, 杨泽栋, 徐家发, 张丽红 数学物理学报(英文版). 2022 (4):  1414-1426.  DOI: 10.1007/s10473-022-0409-0 摘要 ( 50 )   RICH HTML PDF   收藏 In this paper, we are concerned with the existence of the positive bounded and blow-up radial solutions of the $(k_{1},k_{2})$-Hessian system $$\begin{equation*} \begin{split} \left\{\begin{array}{l}{\mathcal{G} (K_{1}^{\frac{1}{k_{1}}}) K_{1}^{\frac{1}{k_{1}}}=b_{1}(|x|) g_{1}(z_{1}, z_{2}), ~~x \in \mathbb{R}^{N}}, \\ {\mathcal{G}(K_{2}^{\frac{1}{k_{2}}}) K_{2}^{\frac{1}{k_{2}}}=b_{2}(|x|) g_{2}(z_{1}, z_{2}), ~~x \in \mathbb{R}^{N}},\end{array}\right. \end{split} \end{equation*}$$ where $\mathcal{G}$ is a nonlinear operator, $K_{i}=S_{k_{i}}\left(\lambda\left(D^{2} z_{i}\right)\right)+\psi_{i}(|x|)|\nabla z_{i}|^{k_{i}},i=1,2.$ Under the appropriate conditions on $g_{1}$ and $g_{2}$, our main results are obtained by using the monotone iterative method and the Arzela-Ascoli theorem. Furthermore, our main results also extend the previous existence results for both the single equation and systems. 参考文献 | 相关文章 | 计量指标

THE MULTIPLICITY AND CONCENTRATION OF POSITIVE SOLUTIONS FOR THE KIRCHHOFF-CHOQUARD EQUATION WITH MAGNETIC FIELDS 王莉, 程琨, 汪继秀 数学物理学报(英文版). 2022 (4):  1453-1484.  DOI: 10.1007/s10473-022-0411-6 摘要 ( 81 )   RICH HTML PDF   收藏 In this paper, we study the multiplicity and concentration of positive solutions for the following fractional Kirchhoff-Choquard equation with magnetic fields: $$\begin{equation*} (a\varepsilon^{2s}+b\varepsilon^{4s-3}[u]^2_{\varepsilon,A/\varepsilon}) (-\Delta)_{A/\varepsilon}^{s} u+V(x)u = \varepsilon^{-\alpha}(I_\alpha*F(|u|^2))f(|u|^2)u\ \ \text{in }\ \mathbb{R}^3. \end{equation*}$$ Here $\varepsilon > 0$ is a small parameter, $a,b > 0$ are constants, $s \in (0% \frac{3} {4} ,1), (-\Delta)_{A}^{s}$ is the fractional magnetic Laplacian, $A: \mathbb{R}^3 \to \mathbb{R}^3$ is a smooth magnetic potential, $I_{\alpha}=\frac{\Gamma(\frac{3-\alpha}{2})}{2^{\alpha}\pi^{\frac{3}{2}}\Gamma(\frac{\alpha}{2})}\cdot\frac{1}{|x|^{\alpha} }$ is the Riesz potential, the potential $V$ is a positive continuous function having a local minimum, and $f: \mathbb{R} \to \mathbb{R}$ is a $C^1$ subcritical nonlinearity. Under some proper assumptions regarding $V$ and $f,$ we show the multiplicity and concentration of positive solutions with the topology of the set $M:= \{x \in \mathbb{R}^3 : V (x) = \inf V \}$ by applying the penalization method and Ljusternik-Schnirelmann theory for the above equation. 参考文献 | 相关文章 | 计量指标

TWO REGULARIZATION METHODS FOR IDENTIFYING THE SOURCE TERM PROBLEM ON THE TIME-FRACTIONAL DIFFUSION EQUATION WITH A HYPER-BESSEL OPERATOR 杨帆, 孙乔夕, 李晓晓 数学物理学报(英文版). 2022 (4):  1485-1518.  DOI: 10.1007/s10473-022-0412-5 摘要 ( 50 )   RICH HTML PDF   收藏 In this paper, we consider the inverse problem for identifying the source term of the time-fractional equation with a hyper-Bessel operator. First, we prove that this inverse problem is ill-posed, and give the conditional stability. Then, we give the optimal error bound for this inverse problem. Next, we use the fractional Tikhonov regularization method and the fractional Landweber iterative regularization method to restore the stability of the ill-posed problem, and give corresponding error estimates under different regularization parameter selection rules. Finally, we verify the effectiveness of the method through numerical examples. 参考文献 | 相关文章 | 计量指标

THE STABILITY OF THE DELTA WAVE TO PRESSURELESS EULER EQUATIONS WITH VISCOUS AND FLUX PERTURBATIONS 刘思杰, 盛万成 数学物理学报(英文版). 2022 (4):  1519-1535.  DOI: 10.1007/s10473-022-0413-4 摘要 ( 86 )   RICH HTML PDF   收藏 This paper is concerned with the pressureless Euler equations with viscous and flux perturbations. The existence of Riemann solutions to the pressureless Euler equations with viscous and flux perturbations is obtained. We show the stability of the delta wave of the pressureless Euler equations to the perturbations; that is, the limit solution of the pressureless Euler equations with viscous and flux perturbations is the delta wave solution of the pressureless Euler equations as the viscous and flux perturbation simultaneously vanish in the case $u_->u_+$. 参考文献 | 相关文章 | 计量指标

TRANSONIC SHOCK SOLUTIONS TO THE EULER SYSTEM IN DIVERGENT-CONVERGENT NOZZLES 段犇, 兰傲, 罗珍 数学物理学报(英文版). 2022 (4):  1536-1546.  DOI: 10.1007/s10473-022-0414-3 摘要 ( 46 )   RICH HTML PDF   收藏 In this paper, we study the transonic shock solutions to the steady Euler system in a quasi-one-dimensional divergent-convergent nozzle. For a given physical supersonic inflow at the entrance, we obtain exactly two non-isentropic transonic shock solutions for the exit pressure lying in a suitable range. In addition, we establish the monotonicity between the location of the transonic shock and the pressure downstream. 参考文献 | 相关文章 | 计量指标

SPACE-LIKE BLASCHKE ISOPARAMETRIC SUBMANIFOLDS IN THE LIGHT-CONE OF CONSTANT SCALAR CURVATURE 宋虹儒, 刘西民 数学物理学报(英文版). 2022 (4):  1547-1568.  DOI: 10.1007/s10473-022-0415-2 摘要 ( 52 )   RICH HTML PDF   收藏 Let $\mathfrak{C}^{m+p+1}_s\subset\mathbb{R}^{m+p+2}_{s+1}$ ($m\geq 2$, $p\geq 1$, $0\leq s\leq p$) be the standard (punched) light-cone in the Lorentzian space $\mathbb{R}^{m+p+2}_{s+1}$, and let $Y:M^m\to \mathfrak{C}^{m+p+1}_s$ be a space-like immersed submanifold of dimension $m$. Then, in addition to the induced metric $g$ on $M^m$, there are three other important invariants of $Y$: the Blaschke tensor $A$, the conic second fundamental form $B$, and the conic Möbius form $C$; these are naturally defined by $Y$ and are all invariant under the group of rigid motions on $\mathfrak{C}^{m+p+1}_s$. In particular, $g,A,B,C$ form a complete invariant system for $Y$, as was originally shown by C. P. Wang for the case in which $s=0$. The submanifold $Y$ is said to be Blaschke isoparametric if its conic Möbius form $C$ vanishes identically and all of its Blaschke eigenvalues are constant. In this paper, we study the space-like Blaschke isoparametric submanifolds of a general codimension in the light-cone $\mathfrak{C}^{m+p+1}_s$ for the extremal case in which $s=p$. We obtain a complete classification theorem for all the $m$-dimensional space-like Blaschke isoparametric submanifolds in $\mathfrak{C}^{m+p+1}_p$ of constant scalar curvature, and of two distinct Blaschke eigenvalues. 参考文献 | 相关文章 | 计量指标

TWO DIMENSIONAL SUBSONIC AND SUBSONIC-SONIC SPIRAL FLOWS OUTSIDE A POROUS BODY 翁上昆, 张子豪 数学物理学报(英文版). 2022 (4):  1569-1584.  DOI: 10.1007/s10473-022-0416-1 摘要 ( 74 )   RICH HTML PDF   收藏 In this paper, we investigate two dimensional subsonic and subsonic-sonic spiral flows outside a porous body. The existence and uniqueness of the subsonic spiral flow are obtained via variational formulation, which tends to a given radially symmetric subsonic spiral flow at far field. The optimal decay rate at far field is also derived by Kelvin’s transformation and some elliptic estimates. By extracting spiral subsonic solutions as the approximate sequences, we obtain the spiral subsonic-sonic limit solution by utilizing the compensated compactness. The main ingredients of our analysis are methods of calculus of variations, the theory of second-order quasilinear equations and the compensated compactness framework. 参考文献 | 相关文章 | 计量指标

CLASSICAL SOLUTIONS OF THE 3D COMPRESSIBLE FLUID-PARTICLE SYSTEM WITH A MAGNETIC FIELD 黄丙远, 丁时进, 伍日清 数学物理学报(英文版). 2022 (4):  1585-1606.  DOI: 10.1007/s10473-022-0417-0 摘要 ( 34 )   RICH HTML PDF   收藏 This paper addresses the 3-D Cauchy problem of a fluid-particle system with a magnetic field. First, the local classical solutions of the linearized model on the sphere $B_{r}$ are obtained by some a priori estimates that do not depend on the radius $r$. Second, the classical solutions of the linearized model in $\mathbb{R}^{3}$ are obtained by combining the continuation and compactness methods. Finally, the classical solutions of the original system are proved by use of the picard iteration argument and the energy method. 参考文献 | 相关文章 | 计量指标

We give some equivalent conditions regarding the above proximinality.

A UNIQUENESS THEOREM FOR HOLOMORPHIC MAPPINGS IN THE DISK SHARING TOTALLY GEODESIC HYPERSURFACES 黄家兴, 吴端伟 数学物理学报(英文版). 2022 (4):  1631-1644.  DOI: 10.1007/s10473-022-0420-5 摘要 ( 47 )   RICH HTML PDF   收藏 In this paper, we prove a Second Main Theorem for holomorphic mappings in a disk whose image intersects some families of nonlinear hypersurfaces (totally geodesic hypersurfaces with respect to a meromorphic connection) in the complex projective space $\mathbb{P}^k$. This is a generalization of Cartan's Second Main Theorem. As a consequence, we establish a uniqueness theorem for holomorphic mappings which intersect $O(k^3)$ many totally geodesic hypersurfaces. 参考文献 | 相关文章 | 计量指标

THE GLOBAL COMBINED QUASI-NEUTRAL AND ZERO-ELECTRON-MASS LIMIT OF NON-ISENTROPIC EULER-POISSON SYSTEMS 杨永富, 琚强昌, 周爽 数学物理学报(英文版). 2022 (4):  1666-1680.  DOI: 10.1007/s10473-022-0422-3 摘要 ( 69 )   RICH HTML PDF   收藏 We consider a non-isentropic Euler-Poisson system with two small parameters arising in the modeling of unmagnetized plasmas and semiconductors. On the basis of the energy estimates and the compactness theorem, the uniform global existence of the solutions and the combined quasi-neutral and zero-electron-mass limit of the system are proved when the initial data are close to the constant equilibrium state. In particular, the limit is rigorously justified as the two parameters tend to zero independently. 参考文献 | 相关文章 | 计量指标

THE METRIC GENERALIZED INVERSE AND ITS SINGLE-VALUE SELECTION IN THE PRICING OF CONTINGENT CLAIMS IN AN INCOMPLETE FINANCIAL MARKET 王紫, 王筱凌, 王玉文 数学物理学报(英文版). 2022 (4):  1681-1689.  DOI: 10.1007/s10473-022-0423-2 摘要 ( 44 )   RICH HTML PDF   收藏 This article continues to study the research suggestions in depth made by M.Z. Nashed and G.F. Votruba in the journal "Bull. Amer. Math. Soc." in 1974. Concerned with the pricing of non-reachable "contingent claims" in an incomplete financial market, when constructing a specific bounded linear operator $A: l_1^n\rightarrow l_2$ from a non-reflexive Banach space $l_1^n$ to a Hilbert space $l_2$, the problem of non-reachable "contingent claims" pricing is reduced to researching the (single-valued) selection of the (set-valued) metric generalized inverse $A^\partial$ of the operator $A$. In this paper, by using the Banach space structure theory and the generalized inverse method of operators, we obtain a bounded linear single-valued selection $A^\sigma=A^+$ of $A^\partial$. 参考文献 | 相关文章 | 计量指标
