Let Ω belong R^n be a smooth hounded domain such that 0∈Ω, N≥3, 2*:=2N/N-2. By using the fibering method introduced by Pohozaev, we prove existence of solutions for a Dirichlet problem associated to a semilinear elliptic equations with critical sobolev exponent and hardy terms -△u-μ/|x|^2u=|u|^2*-2u+λu for suitable p...
