Oscillation Criteria of Nonlinear Delay Partial Diffrence Equations with Continuous Variables

摘要

Partial diffrence equations are diffrence equations that involve functions with two or more independent variables. Such equations arise from considerations of random walk problems, molecular structure problems and numerical diffrence approximation problems and so on.This paper is concerned with a class of the nonlinear delay partial diffrence equations with continuous variables. Some oscillation criteria are obtained. Our result extend some known oscillation results.
