Least action nodal solutions for a quasilinear defocusing Schrodinger equation with supercritical nonlinearity

In this paper, we consider the existence of least action nodal solutions for the quasilinear defocusing Schrodinger equation in H-1(R-N): -Delta u vertical bar k/2u Delta u2 vertical bar V(x)u = g(u)vertical bar lambda vertical bar u vertical bar(p-2)u, where N >= 3, V (x) is a positive continuous potential, g(u) is of subcritical growth, p >= 2* = 2N/(N - 2) and lambda, k are two non- negative parameters. By considering a minimizing problem restricted on a partial Nehari manifold, we prove the existence of least action nodal solution via deformation flow arguments and L-infinity-estimates.
