【Abstract】 The oscillation of solutions of a class of impulsive delay parabolic partial differential system with nonlinear diffusion term is studied.By employing Green./s formula,vertical additive method and impulsive delay differential inequalities,sufficient conditions for oscillation of such systems are obtained under Robin boundary condition.The results fully reflect the influence action of impulsive and delay in system oscillation.更多还原
