报告摘要

We consider a singularly   perturbed elliptic problem on a smooth two dimensional bounded domain.

Let $\Gamma$ be a curve   intersecting orthogonally with the boundary at exactly two points and   dividing the domain into two parts. Moreover, $\Gamma$ satisfies stationary   and non-degeneracy conditions with respect to the arc length functional . We prove   the existence of a solution concentrating along the whole of $\Gamma$,   exponentially small at any positive distance from it, provided that small   parameter is small and away from certain critical numbers. In particular,   this establishes the validity of the two dimensional case of a conjecture by   A. Ambrosetti, A. Malchiodi and W.-M. Ni (p.327, Indiana Univ. Math. J. 53   (2004), no. 2).

  

This is a joint work with   Suting Wei and Bin Xu.
