利用变分法研究了具有Dirichlet边值问题-△u-μ(u/(|x|~2))=f(x,u)的解的存在性问题,在适当的条件下给出了其解的存在性定理.
We consider the following semilinear elliptic equation—△u—μ(u/(|(?)2|))= f(x,u) with the Dirichlet boundary value,and under suitable assumptions on the nonlinear term f.Some existence results of solutions are given via the variational method.
