摘要
研究了一类多时滞抛物型微分方程组解的振动性质,利用一阶脉冲微分不等式获得该类方程组在两类齐次边界条件下判别其若干解振动的充分条件.
In this paper, oscillation of solutions for systems for a class of nonlinear impulsive parabolic eguations with several delays is discussed. A sufficient condition for oscillations is obtained under two kinds of different boundary conditions by using first order impulsive differential inequalities.
