We present some new oscillation criteria for second-order neutral partial functional differential equations of the form , , where is a bounded domain in the Euclidean -space with a piecewise smooth boundary and is the Laplacian in . Our results improve some known results and show that the oscillation of some second-order linear ordinary differential equations implies the oscillation of relevant nonlinear neutral partial functional differential equations.
