Existence of infinitely many radial solutions for quasilinear Schrodinger equations

Gui Bao, Zhi-Qing Han

Abstract:
In this article we prove the existence of radial solutions with arbitrarily many sign changes for quasilinear Schrodinger equation
$$
 -\sum_{i,j=1}^{N}\partial_j(a_{ij}(u)\partial_iu)
 +\frac{1}{2}\sum_{i,j=1}^{N}a'_{ij}(u)\partial_iu\partial_ju+V(x)u
 =|u|^{p-1}u,~x\in\mathbb{R}^N,
 $$
where $N\geq3$, $p\in(1,\frac{3N+2}{N-2})$. The proof is accomplished by using minimization under a constraint.
