Consider the problem {-Delta u + f(|x|/lambda)u/lambda(2) = |u|(4/N-2)u in B-1, u = 0 on partial derivative B-1, where B-1 denotes the open unit ball in R-N, N >= 3 and lambda > 0. Under some general assumptions on f, we prove the existence or the non-existence of radial solutions. We consider also the case when lambda is determined. (C) 2008 Elsevier Inc. All rights reserved.
