The oscillation of a class of impulsive vector neutral parabolic partial differential equations is studied. To change the multi-dimensional oscillation problems into the problems of which one-dimensional impulsive delay differential inequalities haven't eventually positive solution by employing the concept of H-oscillation introduced by Domslak and the method of reducing dimension with the inner product, some sufficient criteria for H-oscillation of all solutions of the equations are established under Dirichle...
