In the large- N limit, conditions for the conformal invariance of the generalized Thirring model are derived, using two different approaches: the background field method and the hamiltonian method based on an operator algebra, and the agreement between them is established.

Description
Summary:In the large- N limit, conditions for the conformal invariance of the generalized Thirring model are derived, using two different approaches: the background field method and the hamiltonian method based on an operator algebra, and the agreement between them is established. A free field representation of the relevant algebra is presented, and the structure of the stress tensor in terms of free fields (and free currents) is studied in detail.
