We consider the oscillatory property of the following -Laplacian equations , . Since there is no Picone-type identity for - Laplacian equations, it is an unsolved problem that whether the Sturmian comparison theorems for -Laplacian equations are valid or not. We obtain sufficient conditions of the oscillatory of solutions for -Laplacian equations.
