Caisheng ChenHongxue Song — 2016

Applications of Mathematics

In this work, we study the existence of nonnegative and nontrivial solutions for the quasilinear Schrödinger equation - Δ N u + b | u | N - 2 u - Δ N ( u 2 ) u = h ( u ) , x N , where Δ N is the N -Laplacian operator, h ( u ) is continuous and behaves as exp ( α | u | N / ( N - 1 ) ) when | u | . Using the Nehari manifold method and the Schwarz symmetrization with some special techniques, the existence of a nonnegative and nontrivial solution u ( x ) W 1 , N ( N ) with u ( x ) 0 as | x | is established.
