On Lepowsky-Wilson's Z-algebra
Y. Hara, M. Jimbo, H. Konno +2
We show that the deformed Virasoro algebra specializes in a certain limit to Lepowsky-Wilson's Z-algebra. This leads to a free field realization of the affine Lie algebra \hat{sl_2…

Beyond CFT : Deformed Virasoro and Elliptic Algebras
S. Odake
In this lecture we discuss `beyond CFT' from symmetry point of view. After reviewing the Virasoro algebra, we introduce deformed Virasoro algebras and elliptic algebras. These alge…

Virasoro-type Symmetries in Solvable Models
H. Awata, H. Kubo, S. Odake +1
Virasoro-type symmetries and their roles in solvable models are reviewed. These symmetries are described by the two-parameter Virasoro-type algebra by choosing the para…
