摘要 讨论了全空间上一类带Hardy-Sobolev临界指数的拟线性椭圆方程{-Δpu-μ|u|p-2 u/|x|p=λ|u|p(t)-2/|x|tu+f(x,u),x∈RNu∈D01,p(RN)其中:D01,p(RN)是C0∞(RN)的闭包,Δpu=-div(|▽u|p-2▽u),2<p<N,0≤μ<=(N-p)p/pp,λ>0,0≤t<p,p<q<p*(t),p*(t)=p(N-t)/(N-t)是Hard-Sobolev临界指数.利用一个新的环绕定理,证明了该方程变号解的存在性. In this paper ,we've studied a class of quasilinear elliptic equation involving Hardy-Sobolev expo-nents - Δp u - μ| u| p-2 u| x | p = λ| u| p* (t)-2| x | t u+ f (x ,u) ,x ∈ RN u ∈ D1 , p0 (RN ) 〈br〉 Where D1,p0 (RN)is C0∞ (RN)closure ,Δpu= -div(|▽ u|p-2 ▽ u) ,2〈 p〈 N ,0≤ μ〈-μ= (N-p)ppp ,λ〉0 ,0≤ t〈 p ,p〈 q〈 p* (t) ,p* (t)= p(N-t)(N-p) is called Hardy-Sobolev critical parameter .By means of a new linking theorem ,the existence of sign-changing solutions has been proved .
