Wightman Functions in Covariant Operator Formalism of Two-Dimensional Quantum Gravity. II: Composite Fields

Abstract

In the covariant operator formalism of two-dimensional quantum gravity, the construction of Wightman functions, presented previously, is extended to the case in which composite fields, i.e., products of fields at the same spacetime point are involved. The Wightman functions thus defined are shown to be consistent with field equations
