This paper is devoted to the investigation of the asymptotic behavior for a class of nonlinear parabolic partial functional differential equations. 本文研究一类非线性抛物型偏泛函微分方程的渐近行为。
Some sufficient conditions are obtained for the oscillation for solutions of systems of second order partial differential equations with several delays. 该文获得了一类具偏差变元的二阶偏泛函微分方程组解振动的若干充分条件。
