Abstract
The following new findings are briefly reported:
-
(a)
A consistent quantum theory can be formulated for a free massless scalar field in two-dimensional spacetime.
-
(b)
Satisfactory operator solutions in terms of asymptotic fields can be constructed in the Thirring and Schwinger models.
-
(c)
Gauge invariance is spontaneously broken in the Thirring model as well as in the Schwinger model.
