This paper is concerned with constructing nodal radial solutions for quasilinear Schrodinger equations in R-N with critical growth which have appeared as several models in mathematical physics. For any given integer k >= 0, by using a change of variables and minimization argument, we obtain a sign-changing minimizer with k nodes of a minimization problem. Since the critical exponent appears and the lower order term may change sign, we should use more delicate arguments. (C) 2013 American...
