چکیده
A new set of realizations of the Virasoro algebra on a bosonic Fock space are found by explicitly computing the Virasoro representations associated with coadjoint orbits of the form DiffS 1 /S 1. Some progress is made in understanding the unitary structure of these representations. The characters of these representations are exactly the bosonic partition functions calculated previously by Witten using perturbative and fixed-point methods. The representations corresponding to the discrete series of unitary Virasoro representations with c ≤ 1 are found to be reducible in this formulation, confirming a conjecture by Aldaya and Navarro-Salas. or The Regents of the University of California.

Let H be the corner-transfer-matrix Hamiltonian for the six-vertex model in the antiferroelectric regime. It acts on the infinite tensor product W = V ⊗ V ⊗ V ⊗ · · ·, where V is the 2-dimensional irreducible representation of the quantum affine Lie algebra Uq ( ŝl (2) ) . We observe that H is the derivation of Uq ( ŝl (2) ) , and conjecture that the eigenvectors of H form the level-1 vacuum re...

We obtain the orbifold Virasoro master equation (OVME) at integer order λ, which summarizes the general Virasoro construction on orbifold affine algebra. The OVME includes the Virasoro master equation when λ = 1 and contains large classes of stress tensors of twisted sectors of conventional orbifolds at higher λ. The generic construction is like a twisted sector of an orbifold (with non-zero gr...

Field-theoretic models for fields taking values in quantum groups are investigated. First we consider SU q (2) σ model (q real) expressed in terms of basic notions of noncommutative differential geometry. We discuss the case in which the σ models fields are represented as products of conventional σ fields and of the coordinate-independent algebra. An explicit example is provided by the U q (2) ...
