摘要:

Bernstein Markov性质(BMP)是对紧集上多项式或有理函数的统一范数增长的渐进行量假设,其中μ为正有限测度。本文考虑两种有理函数的BMP变体,比较其与多项式BMP的关系,发现后者能推出前者的一些充分条件。此外,本文恢复了测量其支持集上满足有理BMP的充分质量密度条件。

英文摘要:

The Bernstein Markov Property, shortly BMP, is an asymptotic quan- titative assumption on the growth of uniform norms of polynomials or rational functions on a compact set with respect to L μ 2 -norms, where μ is a positive finite measure. We consider two variants of BMP for rational functions with restricted poles and compare them with the polynomial BMP finding out some sufficient condi- tions for the latter to imply the former. Moreover, we recover a sufficient mass- density condition for a measure to satisfy the rational BMP on its support.
