Group of currents in the Thirring model and its representations
Abstract
The Gel'fandAraki method is used to construct universally covariant representations of the group of currents in the Thirring model. The currents are represented as infinitesimal generators of suitable oneparameter subgroups. The determination of the generators of the twodimensional Poincare group is discussed, and the existence of a selfadjointed Hamiltonian is demonstrated. The possibility of defining the relation between charges and the values which determine the representation of the group of currents in the Thirring model is investigated.
