共形块、$q$ -组合学和量子群对称性

Conformal blocks, $q$-combinatorics, and quantum group symmetry

Alex Karrila, Kalle Kytölä, Eveliina Peltola

摘要:

在这篇文章中,我们找到了一个$q$ -模拟Fomin的公式。原始的Fomin公式将随机游走漂移核的行列式与环擦除随机游走配分函数联系起来,我们的公式类似地将共形场论的共形块函数与多个SLE随机曲线的纯配分函数联系起来。我们还提供了一种基于量子群的共形块函数的构造方法,即$\mathfrak{sl}_2$的$q$ -变形。该构造既突出了共形块函数的表示理论起源,又解释了$q$ -组合公式的出现。

英文摘要:

In this article, we find a $q$-analogue for Fomin's formulas. The original Fomin's formulas relate determinants of random walk excursion kernels to loop-erased random walk partition functions, and our formulas analogously relate conformal block functions of conformal field theories to pure partition functions of multiple SLE random curves. We also provide a construction of the conformal block functions by a method based on a quantum group, the $q$-deformation of $\mathfrak{sl}_2$. The construction both highlights the representation theoretic origin of conformal block functions and explains the appearance of $q$-combinatorial formulas.
