This paper is devoted to the investigation of the asymptotic behavior for a class of nonlinear parabolic partial functional differential equations. 本文研究一類非線性拋物型偏泛函微分方程的漸近行為。
Some sufficient conditions are obtained for the oscillation for solutions of systems of second order partial differential equations with several delays. 該文獲得了一類具偏差變元的二階偏泛函微分方程組解振動的若干充分條件。
