In this paper, we used variational method to consider the following quasilinear elliptic equation involving Hardy singular term and Sobolev critical exponent:where N ? 3, N > p ? 2, 0? ?<?=(N-p/p)p,p*=Np/N-p is Sobolev critical exponent and g(x) ? 0, g(x)(?)0. We show that if g(x)?Lp*/p*-1(RN) then the above problem has at least two nontrivial solutions. One solution is obtained by local extremum method and the other is obtained by using mountain pass lemma. |
