Quantum Group and -Virasoro Current in Fermion Systems
arXiv:hep-th/9312174 · doi:10.1143/ptp/93.1.195
Abstract
We discuss a generalization of the quantum group $\su$ to the -Virasoro algebra in two-dimensional electrons system under uniform magnetic field. It is shown that the integral representations of both algebras are reduced to those in a (1+1)-dimensional fermion. As an application of the quantum group symmetry, we discuss a model of quantum group current on the analogy of the Hall current.
