Free-Field Representation of Group Element for Simple Quantum Group
Alexei Morozov, Luc Vinet
A representation of the group element (also known as ``universal -matrix'') which satisfies , is given in the form $$ g = \left(\prod_{s=1}^{d_B}\phant…
On a Bosonic-Parafermionic Realization of
A. Hamid Bougourzi, Luc Vinet
We realize the current algebra at arbitrary level in terms of one deformed free bosonic field and a pair of deformed parafermionic fields. It is shown that t…
A Quantum Analogue of the Boson-Fermion Correspondence
A. Hamid Bougourzi, Luc Vinet
We review the classical boson-fermion correspondence in the context of the current algebra at level 2. This particular algebra is ideal to exhibit this correspond…
On a c-number quantum -function
A. Mironov, A. Morozov, L. Vinet
We first review the properties of the conventional -functions of the KP and Toda-lattice hierarchies. A straightforward generalization is then discussed. It corresponds to passi…
