Zero modes' fusion ring and braid group representations for the extended chiral su(2) WZNW model

P. Furlan, L. Hadjiivanov, I. Todorov

The zero modes' Fock space for the extended chiral $su(2)$ WZNW model gives room to a realization of the Grothendieck fusion ring of representations of the restricted $U_{q}sl(2)$ q…
