    Martin G. GRIGORYAN, Stepan SARGSYAN
    数学物理学报(英文版). 2017 (2):  293-300.  DOI: 10.1016/S0252-9602(17)30002-4

    In this article, we prove the following statement that is true for both unbounded and bounded Vilenkin systems:for any ε ∈(0,1), there exists a measurable set E ∈[0,1) of measure bigger than 1-ε such that for any function fL1[0,1), it is possible to find a function gL1[0,1) coinciding with f on E and the absolute values of non zero Fourier coefficients of g with respect to the Vilenkin system are monotonically decreasing.

    UNIFORM QUASI-DIFFERENTIABILITY OF SEMIGROUP TO NONLINEAR BEACTION-DIFFUSION EQUATIONS WITH SUPERCRITICAL EXPONENT
    钟延生, 孙春友
    数学物理学报(英文版). 2017 (2):  301-315.  DOI: 10.1016/S0252-9602(17)30003-6

    A new approach is established to show that the semigroup {S (t)}t ≥ 0 generated by a reaction-diffusion equation with supercritical exponent is uniformly quasi-differentiable in Lq(Ω) (2 ≤ q < ∞) with respect to the initial value. As an application, this proves the upper-bound of fractal dimension for its global attractor in the corresponding space.

    ON COLLISION LOCAL TIME OF TWO INDEPENDENT FRACTIONAL ORNATEIN-UHLENBECK PROCESSES
    郭精军, 李楚进
    数学物理学报(英文版). 2017 (2):  316-328.  DOI: 10.1016/S0252-9602(17)30004-8

    In this article, we study the existence of collision local time of two independent d-dimensional fractional Ornstein-Uhlenbeck processes XtH1 and XtH2, with different parameters Hi ∈ (0,1), i=1,2. Under the canonical framework of white noise analysis, we characterize the collision local time as a Hida distribution and obtain its' chaos expansion.

    PARTIAL STABILITY ANALYSIS OF SOME CLASSES OF NONLINEAR SYSTEMS
    Alexander ALEKSANDROV, Elena ALEKSANDROVA, Alexey ZHABKO, 陈阳舟
    数学物理学报(英文版). 2017 (2):  329-341.  DOI: 10.1016/S0252-9602(17)30005-X

    A nonlinear differential equation system with nonlinearities of a sector type is studied. Using the Lyapunov direct method and the comparison method, conditions are derived under which the zero solution of the system is stable with respect to all variables and asymptotically stable with respect to a part of variables. Moreover, the impact of nonstationary perturbations with zero mean values on the stability of the zero solution is investigated. In addition, the corresponding time-delay system is considered for which delay-independent partial asymptotic stability conditions are found. Three examples are presented to demonstrate effectiveness of the obtained results.

    IMPROVED GRAOIENT METHOD FOR MONOTONE AND LIPSCHITZ CONTINUOUS MAPPINGS IN BANACH SPACES
    Kazuhide NAKAJO
    数学物理学报(英文版). 2017 (2):  342-354.  DOI: 10.1016/S0252-9602(17)30006-1

    Let C be a nonempty closed convex subset of a 2-uniformly convex and uniformly smooth Banach space C and {An}n∈N be a family of monotone and Lipschitz continuos mappings of C into E*. In this article, we consider the improved gradient method by the hybrid method in mathematical programming[10] for solving the variational inequality problem for {An} and prove strong convergence theorems. And we get several results which improve the well-known results in a real 2-uniformly convex and uniformly smooth Banach space and a real Hilbert space.

    SYNCHRONIZATION OF MASTER-SLAVE MARKOVIAN SWITCHING COMPLEX DYNAMICAL NETWORKS WITH TIME-VARYING DELAYS IN NONLINEAR FUNCTION VIA SLIDING MODE CONTROL
    M. Syed ALI, J. YOGAMBIGAI, 曹进德
    数学物理学报(英文版). 2017 (2):  368-384.  DOI: 10.1016/S0252-9602(17)30008-5

    In this article, a synchronization problem for master-slave Markovian switching complex dynamical networks with time-varying delays in nonlinear function via sliding mode control is investigated. On the basis of the appropriate Lyapunov-Krasovskii functional, introducing some free weighting matrices, new synchronization criteria are derived in terms of linear matrix inequalities (LMIs). Then, an integral sliding surface is designed to guarantee synchronization of master-slave Markovian switching complex dynamical networks, and the suitable controller is synthesized to ensure that the trajectory of the closed-loop error system can be driven onto the prescribed sliding mode surface. By using Dynkin's formula, we established the stochastic stablity of master-slave system. Finally, numerical example is provided to demonstrate the effectiveness of the obtained theoretical results.

    ALMOST CONSERVATION LAWS AND GLOBAL ROUGH SOLUTIONS OF THE DEFOCUSING NONLINEAR WAVE EQUATION ON R2
    张再云, 黄建华, 孙明保
    数学物理学报(英文版). 2017 (2):  385-394.  DOI: 10.1016/S0252-9602(17)30009-7

    In this article, we investigate the initial value problem(IVP) associated with the defocusing nonlinear wave equation on R2 as follows:

    where the initial data (u0, u1) ∈ Hs(R2Hs-1(R2). It is shown that the IVP is global well-posedness in Hs(R2Hs-1(R2) for any 1 > s > 2/5. The proof relies upon the almost conserved quantity in using multilinear correction term. The main difficulty is to control the growth of the variation of the almost conserved quantity. Finally, we utilize linear-nonlinear decomposition benefited from the ideas of Roy[1].

    GLOBAL REGULARITY TO THE 2D INCOMPRESSIBLE MHD WITH MIXED PARTIAL DISSIPATION AND MAGNETIC DIFFUSION IN A BOUNDED DOMAIN
    于海波
    数学物理学报(英文版). 2017 (2):  395-404.  DOI: 10.1016/S0252-9602(17)30010-3

    This article considers the global regularity to the initial——boundary value problem for the 2D incompressible MHD with mixed partial dissipation and magnetic diffusion. To overcome the difficulty caused by the vanishing viscosities, we first establish the elliptic system for ux and by, which are estimated by ▽×ux and ▽×by, respectively. Then, we establish the global estimates for ▽×u and ▽×b.

    BOUND STATES OF SCHRÖDINGER EQUATIONS WITH ELECTROMAGNETIC FIELDS AND VANISHING POTENTIALS
    巴娜, 代晋军
    数学物理学报(英文版). 2017 (2):  405-424.  DOI: 10.1016/S0252-9602(17)30011-5

    We study the bound states to nonlinear Schrödinger equations with electromagnetic fields ih (∂ψ/∂t)=(h/i▽-A(x))2ψ + V(x)ψ-K(x)|ψ|p-1ψ=0, on R+×RN. Let G (x)=[V (x)](p+1)/(p-1)-N/2[K(x)]-2/(p-1) and suppose that G(x) has k local minimum points. For h > 0 small, we find multi-bump bound states ψh(x, t)=e-iEt/h uh(x) with uh concentrating at the local minimum points of G(x) simultaneously as h → 0. The potentials V (x) and K(x) are allowed to be either compactly supported or unbounded at infinity.

    数学物理学报(英文版). 2017 (2):  425-438.  DOI: 10.1016/S0252-9602(17)30012-7

    Let p > 0 and μ be a normal function on[0,1), ν(r)=(1-r2)1+(n/p) μ(r) for r ∈[0,1). In this article, the bounded or compact weighted composition operator Tφ,ψ from the μ-Bergman space Ap(μ) to the normal weight Bloch type space βν in the unit ball is characterized. The briefly sufficient and necessary condition that the composition operator Cφ is compact from Ap(μ) to βν is given. At the same time, the authors give the briefly sufficient and necessary condition that Cφ is compact on βu for a > 1.

    THE LARGEST EIGENVALUE DISTRIBUTION OF THE LAGUERRE UNITARY ENSEMALE
    Shulin LYU, Yang CHEN
    数学物理学报(英文版). 2017 (2):  439-462.  DOI: 10.1016/S0252-9602(17)30013-9

    We study the probability that all eigenvalues of the Laguerre unitary ensemble of n by n matrices are in (0,t), that is, the largest eigenvalue distribution. Associated with this probability, in the ladder operator approach for orthogonal polynomials, there are recurrence coefficients, namely, αn(t) and βn(t), as well as three auxiliary quantities, denoted by rn(t), Rn(t), and σn(t). We establish the second order differential equations for both βn(t) and rn(t). By investigating the soft edge scaling limit when α=O(n) as n or→∞ or α is finite, we derive a P, the σ-form, and the asymptotic solution of the probability. In addition, we develop differential equations for orthogonal polynomials Pn(z) corresponding to the largest eigenvalue distribution of LUE and GUE with n finite or large. For large n, asymptotic formulas are given near the singular points of the ODE. Moreover, we are able to deduce a particular case of Chazy's equation for ρ(t)=Ξ'(t) with Ξ(t) satisfying the σ-form of PIV or PV.

    SOME PROPERTIES OF DOUBLE DESIGNS IN TERMS OF LEE DISCREPANCY
    邹娜, 覃红
    数学物理学报(英文版). 2017 (2):  477-487.  DOI: 10.1016/S0252-9602(17)30015-2

    Doubling is a simple but powerful method of constructing two-level fractional factorial designs with high resolution. This article studies uniformity in terms of Lee discrepancy of double designs. We give some linkages between the uniformity of double design and the aberration case of the original one under different criteria. Furthermore, some analytic linkages between the generalized wordlength pattern of double design and that of the original one are firstly provided here, which extend the existing findings. The lower bound of Lee discrepancy for double designs is also given.

    数学物理学报(英文版). 2017 (2):  503-510.  DOI: 10.1016/S0252-9602(17)30017-6

    A Banach space operator satisfies generalized Rako?evi?'s property (gw) if the complement of its upper semi B-Weyl spectrum in its approximate point spectrum is the set of eigenvalues of T which are isolated in the spectrum of T. In this note, we characterize hypecyclic and supercyclic operators satisfying the property (gw).

    数学物理学报(英文版). 2017 (2):  511-526.  DOI: 10.1016/S0252-9602(17)30018-8

    We consider the vibration of elastic thin plates under certain reasonable assump-tions. We derive the nonlinear equations for this model by the Hamilton Principle. Under the conditions on the hyperbolicity for the initial data, we establish the local time well-posedness for the initial and boundary value problem by Picard iteration scheme, and obtain the estimates for the solutions.

    数学物理学报(英文版). 2017 (2):  555-572.  DOI: 10.1016/S0252-9602(17)30021-8

    In this article,we study the following nonhomogeneous Schrödinger-Poisson equations

    where λ > 0 is a parameter.Under some suitable assumptions on V,K,f and g,the existence of multiple solutions is proved by using the Ekeland's variational principle and the Mountain Pass Theorem in critical point theory.In particular,the potential V is allowed to be signchanging.
