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 摘要 ( 61 )   RICH HTML PDF   收藏 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. 参考文献 | 相关文章 | 计量指标

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 摘要 ( 69 )   RICH HTML PDF   收藏 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. 参考文献 | 相关文章 | 计量指标

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 摘要 ( 64 )   RICH HTML PDF   收藏 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(R2)×Hs-1(R2). It is shown that the IVP is global well-posedness in Hs(R2)×Hs-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]. 参考文献 | 相关文章 | 计量指标

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. 参考文献 | 相关文章 | 计量指标

THE COMPACT COMPOSITION OPERATOR ON THE μ-BERGMAN SPACE IN THE UNIT BALL 黎深莲, 张学军, 徐思 数学物理学报(英文版). 2017 (2):  425-438.  DOI: 10.1016/S0252-9602(17)30012-7 摘要 ( 69 )   RICH HTML PDF   收藏 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. 参考文献 | 相关文章 | 计量指标

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 摘要 ( 39 )   RICH HTML PDF   收藏 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 PⅡ, 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. 参考文献 | 相关文章 | 计量指标

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 摘要 ( 49 )   RICH HTML PDF   收藏 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. 参考文献 | 相关文章 | 计量指标
