【Abstract】 This paper discusses the oscillation of solutions for nonlinear neutral partial differential equation in the form of Sufficient conditions are obtained for oscillation of solutions,of this equation, which extend and improve some known results. Where n is bounded domain in R" with piecewise smooth boundary and △is the Laplacian in Euclidean n -space R".更多还原
