β变形的挑战

Challenges of beta-deformation

A. Morozov

摘要:

简要回顾在β变形研究中出现的问题,也被称为“细化”,这在一些相关的现代学科中是一个中心难点:β \neq 1负责偏离2d共形理论中的自由费米子,偏离4d SYM理论中的瞬子和中ε 2 = -ε 1的对称ω背景,从本征值矩阵模型到β-系综,从HOMFLY到Chern-Simons理论中的超多项式,从量子群到椭圆代数和双曲代数等,主要关注AGT关系及其可能的推广。

英文摘要:

A brief review of problems, arising in the study of the beta-deformation, also known as "refinement", which appears as a central difficult element in a number of related modern subjects: beta \neq 1 is responsible for deviation from free fermions in 2d conformal theories, from symmetric omega-backgrounds with epsilon_2 = - epsilon_1 in instanton sums in 4d SYM theories, from eigenvalue matrix models to beta-ensembles, from HOMFLY to super-polynomials in Chern-Simons theory, from quantum groups to elliptic and hyperbolic algebras etc. The main attention is paid to the context of AGT relation and its possible generalizations.
