In this paper, we will study the large scale structure formation using the gravitational partition function. We will assertively argue that the system of gravitating galaxies can be analyzed using the Tsallis statistical mechanics. The divergences in the Tsallis gravitational partition function can be removed using the mathematical riches of the generalization of the dimensional regularization (GDR). The finite gravitational partition function thus obtained will be used to evaluate the thermodynamics of the system of galaxies and thus, to understand the clustering of galaxies in the universe. The correlation function which is beleived to contain the information of clustering of galaxies will also be discussed in this formalism.

星系系统的有限Tsallis引力分配函数
在本文中,我们将使用重力分配函数研究大型结构的形成。我们将坚决主张可以使用Tsallis统计力学来分析引力星系系统。可以使用尺寸正则化(GDR)泛化的数学丰富度来消除Tsallis重力分配函数中的差异。由此获得的有限重力分配函数将用于评估星系系统的热力学,从而了解宇宙中星系的聚集。这个形式主义还将讨论被认为包含星系聚类信息的相关函数。
