Positivity conditions in some indefinite metric quantum field theory models

Three indefinite metric quantum field theory models are studied. The indefinite metric character of each model is due to the fact that the free massless scalar field in two-dimensional space-time must be realized on an indefinite metric vector space. Positivity conditions are proven for each model. For the first model, the exponential of the free massless scalar field, a positivity result is obtained for a special combination of these fields. The positive definite conditions for the Schroer model are proven next. Finally, a direct proof that Klaiber's vacuum expectation values for the Thirring model satisfy the positive definite conditions is given.
