摘要:考虑奇异方程-Δpu=|u|r-2u+(|u|p(s)-2u)/(|x|s)+f(x,u)解的存在性,研究了其所对应的变分泛函的(P.S.)序列,给出了一个局部紧性结果,选择特殊的山路定理和能量估计,证明了方程所对应的变分泛函满足局部的(P.S.)条件时,则存在一个山路型的临界点.

Abstract: The author deals with the conditions of the existence of the singular elliptic equation -Δpu=|u|r-2u+( |u|p(s)-2u)/(|x|s)+ f(x,u). An analysis on the (P.S.) sequence of the variational functionals corresponding to the equations is given and a local compactness result is obtained.By choosing special Mountain Pass theorem and energy estimate,the author obtains that if  the variational functionals corresponding to the equations satisfy local (P.S.) condition,there exsits a critical point,then the author proves the  exitence of positive solutions.

Key words: singularity, variational method, sobolev embedding, hardy inequality
