固定点和融合环。第1部分

Fixed points and fusion rings. Part 1

Elaine Beltaos

摘要:

在这个两部分系列的第一部分中,我们找到了“不动点因式分解”公式,以理解WZW模型的融合环。固定点分解是指对包含由简单电流固定的初级场的CFT的数据进行简化。到目前为止,它只适用于SU(n),在那里它已经发展成为理解CFT的WZW模型的融合环的强大工具-例如,它导致了NIM代表和D-膜电荷和电荷群的封闭公式。在本文中,我们将这些公式推广到其他经典代数,为将来在融合环上的应用打下基础(第2部分)。我们还讨论了与缠绕字符Fuchs-Schellekens-Schweigert的连接。

英文摘要:

In the first of this two-part series, we find `fixed point factorisation' formulas, towards an understanding of the fusion ring of WZW models. Fixed-point factorisation refers to the simplifications in the data of a CFT involving primary fields fixed by simple-currents. Until now, it has been worked out only for SU(n), where it has developed into a powerful tool for understanding the fusion rings of WZW models of CFT -- e.g. it has lead to closed formulas for NIM-reps and D-brane charges and charge-groups. In this paper, we generalise these formulas to the other classical algebras, laying the groundwork for future applications to fusion rings (Part 2). We also discuss connections with the twining characters of Fuchs-Schellekens-Schweigert.
