摘要:
In this paper we deal with semilinear elliptic problem of the form -epsilon (2) Deltau + V(z) u = f(u), in R-2 u is an element of C-2(R-2) boolean AND H-1(R-2), u > 0, in R-2, where a is a small positive parameter, V: R-2 --> lib is a positive potential bounded away from zero, and f(u) behaves like exp(alphas(2)) when s --> + infinity. We prove the existence of solutions concentrating around a local minima not necessarily nondegenerate of V(x), when a tends to 0. (C) 2001 Academic Press.
