二阶双参数混合型偏差分方程解的振动性
Oscillation of Second-Order Mixed Partial Difference Equation with Two Constant Coefficients
摘要
Abstract
We invesigated the oscillation of the solution of the second-order mixed partial difference equation with two constant coefficients pUm+ 2 ,n+ qUm,n+2 -Um,n + Um+ σ,n-τ=0 by using the envelope theory ,and obtained three necessary and sufficient conditions for the oscillation of solutions of the equation ,w here σand τare positive integers , m and n are non-negative integers , p and q are real numbers .关键词
