Title: An existence result for elliptic
       problems with singular critical growth

Author: Yasmina Nasri (Univ. de Tlemcen, Algerie)

Abstract:
 We prove the existence of nontrivial solutions for the singular critical
 problem 
 $$
 -\Delta u-\mu \frac{u}{|x|^{2}}=\lambda f(x)u+u^{2^{\ast }-1}
 $$
 with Dirichlet boundary conditions. Here the domain is a smooth bounded
 subset of $\mathbb{R}^N$, $N\geq 3$, and $2^{\ast }=\frac{2N}{N-2}$ 
 which is the critical Sobolev exponent.
