✦ Synopsis

The functional integral for a four-dimensional abelian anomalous gauge theory is constructed by taking constraints and anomalies into account. It is found to differ from the nai've Lagrangian form. A gauge invariant reformulation is possible, provided (gauge-) covariant anomalies are used. In both formulations, Lorentz invariance seems to be violated. The twodimensional chiral Schwinger model, if treated in the same way, leads to the familiar gauge invariant formulation which is Lorentz invariant.

An algorithm is shown for the calculation of the exact partition function of finite system in four-dimensional \(Z(2)\) lattice gauge theory. The partition functions to the size \(2 \times 2 \times 2 \times 1\) are given. From them, zero-point distribution of the partition functions and the strong c
