Infinitely many solutions of a symmetric semilinear elliptic equation on an unbounded domain

Maad, Sara LU (2003) In Arkiv for Matematik 41(1). p.105-114
Abstract
We study a semilinear elliptic equation of the form
−Δu+u=f(x,u),u∈H^1_0(Ω),
wheref is continuous, odd in u and satisfies some (subcritical) growth conditions. The domain Ω⊂R^N is supposed to be an unbounded domain (N≥3). We introduce a class of domains, called strongly asymptotically contractive, and show that for such domains Ω, the equation has infinitely many solutions.
