研究了一类最佳Hardy—Sobolev常数的达到函数,运用分析技巧对这类极值函数进行了全面的截断估计,并证明了极值函数的渐近性质,这些估计结果是研究此类拟线性椭圆方程的前期基础工作之一.
In this paper,a kind of extremal functions for the best Hardy-Sobolev constant are studied,the cut-off error estimates and the asymptotic properties Ior the extremals are verified by analytic technique. These results are crucial and important for the study of the corresponding quasilinear elliptic problem.
