摘要

本文研究了两类边界条件下有振动系数的脉冲时滞抛物型方程解的振动性,得到了若干解振动的判别准则。其结果即使用于有固定符号系数的方程,也显著地改进了已有的结果。

Abstract

In this paper, oscillation properties of solutions under two boundary condi- tions for impulsive delay parabolic equations with oscillatory coefficients are studied. Several oscillation criteria are obtained. The results of this paper improve some known onse.
