Spike-layered solutions of singularly perturbed elliptic problems in a degenerate setting
M Del Pino, PL Felmer - Indiana University Mathematics Journal, 1999 - JSTOR
In this paper we consider a class of nonlinear singularly perturbed elliptic problems of the
form ε2Δu− u+ f (u)= 0 in Ω, for a superlinear, subcritical function f. Here Ω is a smooth
bounded domain, ε> 0 is a small parameter and we are interested in positive solutions to this
equation satisfying zero Dirichlet or Neumann boundary conditions on∂ Ω. In the study of
the asymptotic behavior of the solutions, when the parameter ε approaches zero, a key role
is played by a uniqueness-nondegeneracy assumption on the limiting equation. Our main …
