酉积分及其相关的矩阵模型

Unitary Integrals and Related Matrix Models

A. Morozov

摘要:

简要回顾酉矩阵积分的基本性质。本文用三种矩阵模型:普通酉模型、Brezin-Gross-Witten模型和Harish-Charndra-Itzykson-Zuber模型对它们进行了研究。特别注意的是棘手的一面的故事,从德威特-特胡夫特异常的酉积分的问题与Itzykson-Zuber措施的分解。强调的技术工具是字符扩展的方法。酉积分的研究还很薄弱,当它引起足够的重视时,人们期待着在这一领域得到许多新的结果。

英文摘要:

Concise review of the basic properties of unitary matrix integrals. They are studied with the help of the three matrix models: the ordinary unitary model, Brezin-Gross-Witten model and the Harish-Charndra-Itzykson-Zuber model. Especial attention is paid to the tricky sides of the story, from De Wit-t'Hooft anomaly in unitary integrals to the problem of correlators with Itzykson-Zuber measure. Of technical tools emphasized is the method of character expansions. The subject of unitary integrals remains highly under-investigated and a lot of new results are expected in this field when it attracts sufficient attention.
