NONLINEAR SEMIGROUP APPROACH TO TRANSPORT EQUATIONS WITH DELAYED NEUTRONS Abdul-Majeed AL-IZERI, Khalid LATRACH 数学物理学报(英文版)    2018, 38 (6): 1637-1654.   摘要 （83）      PDF       收藏 This paper deal with a nonlinear transport equation with delayed neutron and general boundary conditions. We establish, via the nonlinear semigroups approach, the existence and uniqueness of the mild solution, weak solution, strong solution and local solution on Lp-spaces (1 ≤ p<+∞). Local and non local evolution problems are discussed. 参考文献 | 相关文章 | 多维度评价 Select 2. REGULARIZATION OF PLANAR VORTICES FOR THE INCOMPRESSIBLE FLOW 曹道珉, 彭双阶, 严树森 数学物理学报(英文版)    2018, 38 (5): 1443-1467.   摘要 （73）      PDF       收藏 In this paper, we continue to construct stationary classical solutions for the incompressible planar flows approximating singular stationary solutions of this problem. This procedure is carried out by constructing solutions for the following elliptic equations where 0 < p < 1, Ω ? R2 is a bounded simply-connected smooth domain, κi (i=1, …, k) is prescribed positive constant. The result we prove is that for any given non-degenerate critical point x0=(x0,1, …, x0,k) of the Kirchhoff-Routh function defined on Ωk corresponding to (κ1, …, κk), there exists a stationary classical solution approximating stationary k points vortex solution. Moreover, as λ → +∞, the vorticity set {y:uλ > κj} ∩ Bδ(x0,j) shrinks to {x0,j}, and the local vorticity strength near each x0,j approaches κj, j=1, …, k. This result makes the study of the above problem with p ≥ 0 complete since the cases p > 1, p=1, p=0 have already been studied in [11, 12] and [13] respectively. 参考文献 | 相关文章 | 多维度评价 Select 3. YAU'S UNIFORMIZATION CONJECTURE FOR MANIFOLDS WITH NON-MAXIMAL VOLUME GROWTH 陈兵龙, 朱熹平 数学物理学报(英文版)    2018, 38 (5): 1468-1484.   摘要 （72）      PDF       收藏 The well-known Yau's uniformization conjecture states that any complete noncompact Kähler manifold with positive bisectional curvature is bi-holomorphic to the Euclidean space. The conjecture for the case of maximal volume growth has been recently confirmed by G. Liu in [23]. In the first part, we will give a survey on the progress. In the second part, we will consider Yau's conjecture for manifolds with non-maximal volume growth. We will show that the finiteness of the first Chern number C1n is an essential condition to solve Yau's conjecture by using algebraic embedding method. Moreover, we prove that, under bounded curvature conditions, C1n is automatically finite provided that there exists a positive line bundle with finite Chern number. In particular, we obtain a partial answer to Yau's uniformization conjecture on Kähler manifolds with minimal volume growth. 参考文献 | 相关文章 | 多维度评价 Select 4. A LIOUVILLE THEOREM FOR STATIONARY INCOMPRESSIBLE FLUIDS OF VON MISES TYPE Martin FUCHS, Jan MÜLLER 数学物理学报(英文版)    2019, 39 (1): 1-10.   DOI: 10.1007/s10473-019-0101-1 摘要 （61）      PDF       收藏 We consider entire solutions u of the equations describing the stationary flow of a generalized Newtonian fluid in 2D concentrating on the question, if a Liouville-type result holds in the sense that the boundedness of u implies its constancy. A positive answer is true for p-fluids in the case p>1 (including the classical Navier-Stokes system for the choice p=2), and recently we established this Liouville property for the Prandtl-Eyring fluid model, for which the dissipative potential has nearly linear growth. Here we finally discuss the case of perfectly plastic fluids whose flow is governed by a von Mises-type stress-strain relation formally corresponding to the case p=1. It turns out that, for dissipative potentials of linear growth, the condition of μ-ellipticity with exponent μ<2 is sufficient for proving the Liouville theorem. 参考文献 | 相关文章 | 多维度评价 Select 5. THE COMBINED INVISCID AND NON-RESISTIVE LIMIT FOR THE NONHOMOGENEOUS INCOMPRESSIBLE MAGNETOHYDRODYNAMIC EQUATIONS WITH NAVIER BOUNDARY CONDITIONS 张志朋 数学物理学报(英文版)    2018, 38 (6): 1655-1677.   摘要 （41）      PDF       收藏 In this paper, we establish the existence of the global weak solutions for the nonhomogeneous incompressible magnetohydrodynamic equations with Navier boundary conditions for the velocity field and the magnetic field in a bounded domain Ω ⊂ R3. Furthermore, we prove that as the viscosity and resistivity coefficients go to zero simultaneously, these weak solutions converge to the strong one of the ideal nonhomogeneous incompressible magnetohydrodynamic equations in energy space. 参考文献 | 相关文章 | 多维度评价 Select 6.

RIGIDITY THEOREMS OF COMPLETE KÄHLER-EINSTEIN MANIFOLDS AND COMPLEX SPACE FORMS 种田, 东瑜昕, 林和子, 任益斌 数学物理学报(英文版)    2019, 39 (2): 339-356.   DOI: 10.1007/s10473-019-0201-y 摘要 （37）      PDF       收藏 We concentrate on using the traceless Ricci tensor and the Bochner curvature tensor to study the rigidity problems for complete Kähler manifolds. We derive some elliptic differential inequalities from Weitzenbock formulas for the traceless Ricci tensor of Kähler manifolds with constant scalar curvature and the Bochner tensor of Kähler-Einstein manifolds respectively. Using elliptic estimates and maximum principle, several Lp and L∞ pinching results are established to characterize Kähler-Einstein manifolds among Kähler manifolds with constant scalar curvature and complex space forms among Kähler-Einstein manifolds. Our results can be regarded as a complex analogues to the rigidity results for Riemannian manifolds. Moreover, our main results especially establish the rigidity theorems for complete noncompact Kähler manifolds and noncompact Kähler-Einstein manifolds under some pointwise pinching conditions or global integral pinching conditions. To the best of our knowledge, these kinds of results have not been reported. 参考文献 | 相关文章 | 多维度评价 Select 8. SIGN-CHANGING SOLUTIONS FOR THE STATIONARY KIRCHHOFF PROBLEMS INVOLVING THE FRACTIONAL LAPLACIAN IN RN 程琨, 高琦 数学物理学报(英文版)    2018, 38 (6): 1712-1730.   摘要 （35）      PDF       收藏 In this paper, we study the existence of least energy sign-changing solutions for a Kirchhoff-type problem involving the fractional Laplacian operator. By using the constraint variation method and quantitative deformation lemma, we obtain a least energy nodal solution ub for the given problem. Moreover, we show that the energy of ub is strictly larger than twice the ground state energy. We also give a convergence property of ub as b↘ 0, where b is regarded as a positive parameter. 参考文献 | 相关文章 | 多维度评价 Select 9.

HERMAN RINGS WITH SMALL PERIODS AND OMITTED VALUES Tarun Kumar CHAKRA, Gorachand CHAKRABORTY, Tarakanta NAYAK 数学物理学报(英文版)    2018, 38 (6): 1951-1965.   摘要 （28）      PDF       收藏 All possible arrangements of cycles of three periodic as well as four periodic Herman rings of transcendental meromorphic functions having at least one omitted value are determined. It is shown that if p=3 or 4, then the number of p-cycles of Herman rings is at most one. We have also proved a result about the non-existence of a 3-cycle and a 4-cycle of Herman rings simultaneously. Finally some examples of functions having no Herman ring are discussed. 参考文献 | 相关文章 | 多维度评价 Select 14.

NUMERICAL ANALYSIS FOR VOLTERRA INTEGRAL EQUATION WITH TWO KINDS OF DELAY 郑伟珊, 陈艳萍 数学物理学报(英文版)    2019, 39 (2): 607-617.   DOI: 10.1007/s10473-019-0222-6 摘要 （25）      PDF       收藏 In this article, we study the Volterra integral equations with two kinds of delay that are proportional delay and nonproportional delay. We mainly use Chebyshev spectral collocation method to analyze them. First, we use variable transformation to transform the equation into an new equation which is defined in [-1, 1]. Then, with the help of Gronwall inequality and some other lemmas, we provide a rigorous error analysis for the proposed method, which shows that the numerical error decay exponentially in L∞ and Lωc2-norm. In the end, we give numerical test to confirm the conclusion. 参考文献 | 相关文章 | 多维度评价 Select 20. ALTERNATING DIRECTION IMPLICIT OSC SCHEME FOR THE TWO-DIMENSIONAL FRACTIONAL EVOLUTION EQUATION WITH A WEAKLY SINGULAR KERNEL 张海湘, 杨雪花, 徐大 数学物理学报(英文版)    2018, 38 (6): 1689-1711.   摘要 （24）      PDF       收藏 In this paper, a new kind of alternating direction implicit (ADI) Crank-Nicolson-type orthogonal spline collocation (OSC) method is formulated for the two-dimensional fractional evolution equation with a weakly singular kernel arising in the theory of linear viscoelasticity. The novel OSC method is used for the spatial discretization, and ADI Crank-Nicolson-type method combined with the second order fractional quadrature rule are considered for the temporal component. The stability of proposed scheme is rigourously established, and nearly optimal order error estimate is also derived. Numerical experiments are conducted to support the predicted convergence rates and also exhibit expected super-convergence phenomena. 参考文献 | 相关文章 | 多维度评价
