We confirm in this paper that the number q(α)=p(N+α)Np with α>0 is exactly the critical exponent for the embedding from the weighted Sobolev space Wr1,p(RN) of radial functions into Lq(RN,|x|α) where 1<p<N. We name q(α) as the upper Hénon–Sobolev critical exponent of the embedding.

径向函数加权Sobolev嵌入的临界指数

我们在本文中确认 qα=pñ+αñ-pα>0 正是从加权Sobolev空间进行嵌入的关键指数 w ^[R1个p[Rñ 径向函数 大号q[Rñ|X|α 哪里 1个<p<ñ。我们命名qα 作为嵌入的上Hénon–Sobolev临界指数。
