本文考虑一类具Hardy-Sobolev临界指数的半线性椭圆方程,通过证明局部(P.S.)条件和能量估计,运用伪指标理论得到了这类方程多解的存在性(见文[1-13]).
We investigate a class of semilinear elliptic equations with Hardy-Sobolev critical exponent. With the aids of pseudoindex theory, multiple nontrivial solutions are obtained by proving local (P.S.) conditon and estimating energy carefully (see [1-13]).
