有限区间上的扩散算子的惟一性定理

讨论了有限区间[0,π]上的扩散算子的逆问题,对固定的整数n(n∈Z),证明不同的系数H_k的扩散算子的第n个特征值的谱集合能够惟一确定势函数[0,π]上的(q(x),p(x))及边界条件中的系数h.

THE FIRST BOUNDARY VALUE PROBLEM FOR STRONGLY DEGENERATE QUASILINEAR PARABOLIC EQUATIONS IN ANISOTROPIC SOBOLEV SPACES

This article concerns the existence of weak solutions of the first boundary value problem for a kind of strongly degenerate quasilinear parabolic equation in the anisotropic Sobolev Space. With the theory of anisotropic Sobolev spaces an existence result is proved.

Existence of Solutions for a Multi-point Boundary Value Problems with Three Dimension Kernal at Resonance

In this paper,a multi-point boundary value problems for a three order nonlinear deferential equation is considered.With the help of coincidence theorem due to Mawhin,a existence theorem is obtained.

EXISTENCE AND UNIQUENESS OF SOLUTIONS TO STOCHASTIC DIFFERENTIAL EQUATION WITH RANDOM COEFFICIENTS

This paper mainly deals with a stochastic differential equation (SDE) with random coefficients. Sufficient conditions which guarantee the existence and uniqueness of solutions to the equation are given.
