| Abstract: | Oscillation of solutions to a class of nonlinear impulsive parabolic differential equations with several delays is discussed under the homogeneous Dirichlet and Neumann boundary conditions.Some sufficient conditions of the impulsive differential inequalities which don't have eventually positive solutions (or eventually negative solutions) are obtained by employing the analysis technique.Then,the oscillation problems are transformed into the impulsive differential inequalities which don't have eventually pos... |
