| Abstract: | In this paper, we investigate oscillatory properties of solutions of certain parabolic partial differential equations and establish a series of sufficient conditions for oscillations of the equations. The results fully indicate that the oscillations are caused by delay. This is one important conclusion and hence, reveals the essential differences between the equations and those equations without delay. |
