| Abstract: | Using linking theorem and analytic technique, we discuss the existence of nontrivial solutions for the following semilinear elliptic problem with Hardy-Sobolev critical exponents and weights - Δ u-μ u |x|2 =λu+K(x) |u|2*(s)-2u |x|s , x∈Ω; u=0, x∈Ω, where Ω is an open bounded domain of R <em>N with smooth boundary Ω and 0∈Ω, N≥5, 02, λ>0, and K (x) is a bounded positive function on Ω. |
