摘要/Abstract

摘要：

该文主要研究了某些解析函数的积分平均范数和由全纯二次微分所诱导的调和 Beltrami 微分间的关系. 讨论了全纯形式满足哪些条件时具有有限渐近方差. 该文利用积分平均范数给出调和 Beltrami 微分属于 Weil-Petersson 类的判别方法. 进一步给出单位圆周上的拟对称同胚 $g$ 属于 Sobolev $H^{3/2}$ 的判别方法.

关键词: 渐近方差, 调和 Beltrami 微分, Weil-Petersson 类.

Abstract:

In this paper we investigate the relationship between the integral averages norms of some analytic functions and the harmonic Beltrami differentials induced by some holomorphic quadratic differentials. We discuss that under what conditions are the holomorphic forms with finite asymptotic variances. The paper offers a new criterion method for a harmonic Beltrami differential belonging to the Weil-Petersson class by the integral means norms. Furthermore we give a method of determining a homeomorphism $g$ of the unit circle $\partial\Delta$ belonging to Sobolev class $H^{\frac{3}{2}}$.

Key words: asymptotic variance, harmonic Beltrami differential, Weil-Petersson class.
