Abstract: | In this paper a class of p-Laplacian equations are considered. The existence of five nontrivial solutions is stated. By the
standard supersolution and subsolution method, we prove the existence of minimal positive solution and maximal negative solution
in L
∞(Ω). Furthermore, in virtue of the well-known Mountain-Pass Theorem and Second Deformation Theorem, we can give additional three
nontrivial solutions, i.e., one positive solution, one negative solution and one sign-changing solution. |
