BRST上同调和广义李代数上同调:一个矩阵模型的分析

The BRST cohomology and a generalized Lie algebra cohomology: analysis of a matrix model

Roberta A. Iseppi

摘要:

本文研究了具有$U(2)$ -规范对称性的矩阵模型的BRST上同调复形。在简要介绍了有限维规范理论中的BV构造和规范固定过程之后,我们将这些构造应用到模型中,目的是明确地确定和计算相应的规范固定的BRST上同调群.在本文的第二部分,我们引入了广义李代数上同调的概念,它允许规范固定的BRST上同调复形的一个新的描述,能够检测一个双复形结构。

英文摘要:

This article is devoted to the analysis of the gauge-fixed BRST cohomology complex for a matrix model endowed with a $U(2)$-gauge symmetry. After a brief introduction on the BV construction and the gauge-fixing procedure in the setting of finite-dimensional gauge theories, we apply these constructions to the model, with the purpose of explicitly determining and computing the corresponding gauge-fixed BRST cohomology groups. In the second part of this article, we introduce a notion of generalized Lie algebra cohomology, which allows the gauge-fixed BRST cohomology complex for a new description, able to detect a double complex structure.
