摘要
利用山路引理和强极值原理证明了一类具Sobolev临界指数Dirichlet问题正强解的存在性,将Brezis和Nirenberg的相关结果延拓到该椭圆边值问题的临界维数空间(三维空间).
An existence theorem of positive strong solution for a Dirichlet problem with the critical Sobolev exponent was given by way of Mountain-Pass Lemma and Strong Minimum Principle, which extended the corresponding results obtained by Brezis and Nirenberg to a three-dimension space, the critical dimension space for the Dirichlet problem.
