Abstract
In this paper, we study the existence and concentration of weak solutions to the p-Laplacian type elliptic problem {fx1-1} where Ω is a domain in ℝN, possibly unbounded, with empty or smooth boundary, ɛ is a small positive parameter, f ∈ C 1(ℝ+, ℝ) is of subcritical and V: ℝN → ℝ is a locally Hölder continuous function which is bounded from below, away from zero, such that infΛ V < min∂Λ V for some open bounded subset Λ of Ω. We prove that there is an ɛ 0 > 0 such that for any ɛ ∈ (0, ɛ 0], the above mentioned problem possesses a weak solution u ε with exponential decay. Moreover, u ε concentrates around a minimum point of the potential V in Λ. Our result generalizes a similar result by del Pino and Felmer (1996) for semilinear elliptic equations to the p-Laplacian type problem.
