AN OPERATOR REGULARIZATION FOR CHIRAL GAUGE-THEORIES

We present a universal regularization of fermionic operators in the canonical formalism which respects all the symmetries which are manifest in that formalism. It allows an a priori discussion of the quantum constraint algebra and makes the formal steps leading to a path integral formula well-defined. We calculate the fermionic contributions to the renormalizations of the Gauss law and verify that the quantum constraint algebra contains Schwinger terms. We suggest a modification in the path integral formula which allows us to recover the classical degrees of freedom.
