本文研究了空间中秩为一的Harish-Chandra-Itzykson-Zuber积分, 极限,其中\frac{N\beta}{2} \到cNβ2→c,称为高温区,并表明它 可以用来构造一个有前途的单参数插值族, 参数c 经典卷积和自由卷积的区别这 C-卷积 有一个简单的解释,在另一个相关的家庭, 分布由c索引, 称为Markov-Krein变换:c卷积 两个分布的卷积对应于它们的经典卷积。 Markov-Krein变换我们推导出第一个累积矩关系, 中心极限定理,泊松极限定理,并显示几个 C-卷积的数值例子 分布。
We study the rank one Harish-Chandra-Itzykson-Zuber integral in the limit where \frac{N\beta}{2} \to cNβ2→c, called the high-temperature regime and show that it can be used to construct a promising one-parameter interpolation family, with parameter c between the classical and the free convolution. This c-convolution has a simple interpretation in terms of another associated family of distribution indexed by c, called the Markov-Krein transform: the c-convolution of two distributions corresponds to the classical convolution of their Markov-Krein transforms. We derive first cumulant-moment relations, a central limit theorem, a Poisson limit theorem and show several numerical examples of c-convoluted distributions.
