Deformations of a 2D charged black hole
Oleg A. Soloviev
We discuss two types of deformations of a 2D black hole carrying an electric charge. Type I gives rise to a space-time configuration similar to the one described by McGuigan, Nappi…
Conformal Invariance of Interacting WZNW Models
O. A. Soloviev
We consider two level WZNW models coupled to each other through a generalized Thirring-like current-current interaction. It is shown that in the large limit, this interacti…
Solutions of the Master Virasoro Equations as Conformal Points of Perturbed WZNW Model
O. A. Soloviev
It is shown that the master equation of the affine-Virasoro construction on the unitary affine algebra naturally emerges in the fusion algebra of the nonunitary level WZNW mode…
A symplectic structure for the space of quantum field theories
E. Ramos, O. A. Soloviev
We use the formal Lie algebraic structure in the ``space'' of hamiltonians provided by equal time commutators to define a Kirillov-Konstant symplectic structure in the coadjoint or…
