Nodal Solutions For Quasilinear Schr(o|¨)dinger Equations With Critical Nonlinearlity And Non-square Dispersion

This paper is concerned with a type of quasilinear Schrodinger equations of the form where λ>0, N>3,4p<q<2p2*,1<p<+oo. For any given k≥0, by using a change of variables and Nehari argument, we obtain a sign-changing minimizer with k nodes.
