无限融合积与$\hat{\mathfrak{sl}_2}$陪集

Infinite fusion products and $\hat{\mathfrak{sl}_2}$ cosets

E. Feigin

摘要:

本文研究不可约可积$\hat{\mathfrak{sl}_2}$表示的张量积的无穷融合积逼近。这给出了相应陪集理论的近似。作为应用,我们将这些理论的空间特征表示为某些限制Kostka多项式的极限。这导致了$\hat{\mathfrak{sl}_2}$分支函数的玻色子(已知)和费米子(新)公式。

英文摘要:

In this paper we study an approximation of tensor product of irreducible integrable $\hat{\mathfrak{sl}_2}$ representations by infinite fusion products. This gives an approximation of the corresponding coset theories. As an application we represent characters of spaces of these theories as limits of certain restricted Kostka polynomials. This leads to the bosonic (which is known) and fermionic (which is new) formulas for the $\hat{\mathfrak{sl}_2}$ branching functions.
