Haar么正元和圆元是Voiculescu自由概率论中最常用的两种分布,它们在冯·诺依曼代数的自由积的研究中有着显著的应用(参见[4,5,11,12,19,20])。本文的出发点是,如果考虑这些分布的R变换(即傅里叶变换的对数的自由模拟),则得到类似性质的表达式。公式为:(I)[R(µ
The Haar unitary and the circular element provide two of the most frequently used ∗-distributions in the free probability theory of Voiculescu, and in its remarkable applicationsto the study of free products of von Neumann algebras (see e.g. [4,5,11,12,19,20]). Thestarting point of the present paper is that if the R-transform (i.e. the free analogue of thelogarithm of the Fourier transform) of these ∗-distributions is considered, then expressionsof a similar nature are obtained. The formulas are:(I) [R(µ
