摘要
This paper deals with the following class of singular biharmonic problems [GRAPHICS] where 1 less than or equal to q < 2* -1, 2* = 2N/(N-4) is the critical Sobolev exponent, Delta(2) denotes the biharmonic operator, Omega is open domain (not necessarily bounded, it may be equal to R-N) and V is a potential that changes sign in Omega with some points of singularities in Omega. Some results on the existence of solutions are obtained by combining the Mountain Pass Theorem and Hardy inequality with some arguments used by Brezis and Nirenberg. (C) 2002 Elsevier Science (USA).
