  摘要 ( ) PDF全文 ( )   可视化   收藏

  This note is a continuation of earlier papers "The Cauchy Problem for General Coupled Maxwell-Schrodinger Equations (I) (II)". When the spatial dimensions are three ,we prove the existence of global small solution for the Cauchy problem of general coupled Maxwell-Schrodinger equations under Lorentz gauge.

  DIAGNOSTICS FOR EMPIRICAL BAYES MODELS

  Jian Qing SHI;Fang Huan WAN

  Journal of Systems Science and Complexity. 1999, 12(2): 104-114.

  In this paper, we study the diagnostic problems of parametric empirical Bayes models systematically. Cook's distance and Kullback-Leibler divergence are used to measure the effect of each individual observation, and the local influence diagnostic is used to assess the influence of minor perturbations on empirical Bayes estimates as well.

  The existence and uniqueness of the local classical solution of nonhomogenuous Hopf equations in higher dimensions are proved in this paper. This solution is obtained by vanishing the viscosity term of Burger's equations in higher dimensions.

  BAHADUR'S REPRESENTATION FOR NEAREST NEIGHBOR MEDIAN ESTIMATES: THE FIXED DESIGN CASE

  Ying YANG;Bing Zhang WANG

  Consider the nonparametric regression model Yi=g(xi) +ei, i=1, 2,...,where g is an unknown function defined on the interval [0, 1], the fixed design points xi(i≥1) are known and ei's are i.i.d. random variables with median zero. The regressor is assumed to take values in [0,1]/in R and the regressand to be real valued.

  A NOTE ON THE PAPER “UNIFORM PERSISTENCE IN DISCRETE SEMIDYNAMICAL SYSTEM AND ITS APPLICATION”

  Zhi Dong TENG

  Journal of Systems Science and Complexity. 1999, 12(2): 145-148.

  摘要 ( ) PDF全文 ( )   可视化   收藏

  In this paper, we study the uniform persistence of a class of two dimensional periodic Kolmogorov ecosystems. As an improvement on a main result in [1] we obtain a new criterion of the uniform persistence for solutions.

  In this paper, a sufficient condition for a balance bipartite graph to have a connected [1, k]-factor is given, which generalizes a known condition of a balance bipartite graph for the existence of a hamilton-path.

  GLOBAL SUPERCONVERGENCE FOR A MIXED FINITE ELEMENT METHOD FOR THE WAVE EQUATION

  Yan Ping CHEN

  This paper treats the lowest-order Raviart-Thomas mixed finite element method for second order hyperbolic equation. The superconvergence phenomena between the finite element solution and its elliptic projection have been observed. Thus a global L~2-superconvergence of O(h~2) is obtained by using one kind of post-processing operator.

  POINCARE BIFURCATIONS IN POLYNOMIAL DIFFERENTIAL SYSTEMS

  Ding Jun LUO

  Journal of Systems Science and Complexity. 1999, 12(2): 166-174.

  The Poincare bifurcations for polynomial differential systems are considered in this paper. Usually, the Pontryagin's method of perturbed Hamiltonian systems are used to deal with such problem by studying the number and multiplicity of the zero points for certain Abelian integrals,and many results have been given for concrete polynomial systems.

  In this paper we consider certain eigenvalue systems. Imposing some reasonable hypotheses, we prove that the eigenvalue system has a unique eigenvalue with positive eigenfunctions, and that the eigenfunction is unique up to a scalar multiple.
