矩阵模型中的q-维拉索罗约束

q-Virasoro constraints in matrix models

Anton Nedelin, Maxim Zabzine

摘要:

维拉索罗约束在矩阵模型的研究以及理解矩阵模型与CFTs之间的关系中起着重要的作用。最近超对称规范理论中的定域计算产生了新的矩阵模型族,而我们对这些矩阵模型的了解非常有限。我们专注于厄米矩阵模型的椭圆推广,该模型对应于$S^3 \times S^1$上矢量多重态的配分函数计算。我们推导出这个矩阵模型的$q$ -维拉索罗约束。我们还观察到$q$ -维拉索罗代数的一些有趣的代数性质。

英文摘要:

The Virasoro constraints play the important role in the study of matrix models and in understanding of the relation between matrix models and CFTs. Recently the localization calculations in supersymmetric gauge theories produced new families of matrix models and we have very limited knowledge about these matrix models. We concentrate on elliptic generalization of hermitian matrix model which corresponds to calculation of partition function on $S^3 \times S^1$ for vector multiplet. We derive the $q$-Virasoro constraints for this matrix model. We also observe some interesting algebraic properties of the $q$-Virasoro algebra.
