该文证明了一个Rellich-Sobolev不等式并且得到了相应的最佳常数.证明过程依赖于球调和分解以及由Adimurthi等所给出的Hardy-Sobolev不等式的最佳常数.
The author proves a Rellich-Sobolev inequality and obtains the corresponding sharp constant. The procedure is based on decomposition into spherical harmonics and the best constant of Hardy-Sobolev inequality given by Adimurthi et al.
