Abstract

We study the asymptotic behavior of radial solutions for a singularly perturbed semi linear elliptic Dirichlet problem on an annulus. We show that Morse index informations on such solutions provide a complete description of the blow-up behavior. As a by-product, we exhibit some sufficient conditions to guarantee that radial ground state solutions blow-up and concentrate at the inner/outer boundary of the annulus.
