Oscillatory Conditions For PDE With P-Laplacian

In this paper,we focus on PDE with p-laplacian:div(|Du|^p-2Du)+c?x?|u|^p-2u=0,p>1,?1?and more generally casediv(|Du|^p-2A?x?Du)+c?x?|u|^p-2u=0,p>1.?2?We discuss the oscillatory conditions of PDE by applying the Riccati technique and general means.Some sufficient conditions for the oscillation of differential equations are obtained,and for some conclusions about the oscillation of PDE are further simplified and promoted.
