C^N中的超限直径概念与范德蒙德行列式的积分

Transfinite diameter notions in C^N and integrals of Vandermonde determinants

T. Bloom, N. Levenberg

摘要:

我们提供了一个一般的框架,并指出超限直径,齐次超限直径和加权超限直径的概念之间的关系在C^N。一个成分是Rumely公式,它将Robin函数与紧集的超限直径联系起来。对于C^N中的一般紧集和测度,我们还证明了广义变权范德蒙德行列式积分的极限公式.我们的结果推广到定义在R^N中锥上的某些权和测度。

英文摘要:

We provide a general framework and indicate relations between the notions of transfinite diameter, homogeneous transfinite diameter, and weighted transfinite diameter for sets in C^N. An ingredient is a formula of Rumely which relates the Robin function and the transfinite diameter of a compact set. We also prove limiting formulas for integrals of generalized Vandermonde determinants with varying weights for a general class of compact sets and measures in C^N. Our results extend to certain weights and measures defined on cones in R^N.
