Wightman Functions in Covariant Operator Formalism of Two-Dimensional Quantum Gravity. III: New Definition
1992
Progress of theoretical physics
In the covariant operator formalism of two-dimensional quantum gravity, the definition of Wightman functions is modified in such a way that the ones involving products of fields at the same spacetime points reproduce those of the conventional quantum field theory when gravity is switched off. The exact expressions for Wightman functions are obtained, and consistency with field equations is discussed. * )
