Title: Entire solutions for a class of p-Laplace equations in R^2
       
Author: Zheng Zhou (Hunan Univ., Changsha, China)

Abstract:
 We study the entire solutions of
 the p-Laplace equation
 $$
 -\hbox{div}(|\nabla u|^{p-2}\nabla u)+a(x,y)W'(u(x,y))=0, \quad
 (x,y)\in {\mathbb{R}}^2
 $$
 where a(x,y) is a periodic in x and y, positive function. Here
 $W:\mathbb{R}\to\mathbb{R}$ is a two well potential. Via variational
 methods,  we show that there is layered solution which is heteroclinic
 in x and periodic in y direction.
