Abstract

In this paper we construct a new kind of positive solutions of \Deuu+up=0onR2\De u-u+u^{p}=0 \text{on} \R^2 when p>2.p> 2. These solutions u(x,z)\om(xf(z))+i=1\om0((x,z)ξie1)\displaystyle{u(x,z)\sim \om(x-f(z))+ \sum_{i=1}^{\infty}\om_{0}((x, z)-\xi_i\vec{e}_{1})} as L+L\rightarrow +\infty where \om\om is a unique positive homoclinic solution of \om"\om+\omp=0\om"-\om+\om^{p}=0 in R\R ; \om0\om_{0} is the two dimensional positive solution and e1=(1,0)\vec{e}_{1}= (1, 0) and ξj\xi_{j} are points such that ξj=jL+O(1)\xi_{j}= jL+ \mathcal{O}(1) for all j1.j\geq 1. This represents a first result on the {\em coexistence} of fronts and bumps. Geometrically, our new solutions correspond to {\em triunduloid} in the theory of CMC surface.
