正交多项式极大熵测度的弱极限

Weak limits of the measures of maximal entropy for Orthogonal polynomials

Carsten Lunde Petersen, Eva Uhre

摘要:

本文研究了由概率测度$μ$定义的具有非极性紧支集$S(μ)\subset\mathbb C$的正交多项式序列$\{P_n(μ; z)\}$。证明了$P_n$的最大熵测度序列$ω_n$的任何弱 * 极限的支撑都包含在$S(μ)$的多项式凸包中。并且对于$n$ -次根正则测度,$ω_n$弱 * 收敛到$S(μ)$上的平衡测度.

英文摘要:

In this paper we study the sequence of orthonormal polynomials $\{P_n(μ; z)\}$ defined by a probability measure $μ$ with non-polar compact support $S(μ)\subset\mathbb C$. We show that the support of any weak* limit of the sequence of measures of maximal entropy $ω_n$ for $P_n$ is contained in the polynomial-convex hull of $S(μ)$. And for $n$-th root regular measures the $ω_n$ converge weak* to the equilibrium measure on $S(μ)$.
