Abstract:It was discussed a class of elliptic equations involving Hardy terms and Sobolev-Hardy critical exponents {-△u-u+h(x)/|x|2u=|u|2·(s)-2/|x|s u+λ|u|q-2 u,x∈Ω; u=0,x∈ Ω.The existence of nontrivial solutions was proved via variational methods and delicate estimates, where Ω R N(N≥3) was an bounded domain with smooth boundary and containing the origin 0,λ〉0,u∈R,0≤s〈2.
Keywords:Hardy inequality  Sobolev-Hardy critical exponents  variational methods  nontrivial solutions
