Abstract:

In this paper, we consider a class of particular (p,2)-Laplacian Dirichlet problem with nonlinearity which is superlinear but does not satisfy the Ambrosetti-Rabinowitz condition at infinity. Some existence results for nontrivial solution are established by Morse theory in the general case 2 < p < N and similar results are also established by combining Morse theory with Moser-Trudinger inequality when p=N.

Key words: (p,2)-Laplacian Dirichlet problem, Morse theory, Subcritical exponential growth, Improved subcritical polynomial growth
