A Note on Invariant Measure on the Local Gauge Group

Wei-Min Sun, Xiang-Song Chen, Fan Wang

In this paper we investigated the problem of the existence of invariant meaures on the local gauge group. We prove that it is impossible to define a {\it finite} translationally in…

A simple proof that $C^{\infty} (R^{n}, U (1))$ does not have a Haar measure

Wei-Min Sun, Xiang-Song Chen, Fan Wang

We give a simple proof that there does not exist a Haar measure on the group $C^{\infty} (R^{n}, U (1))$ .

A Note on Functional Integral over the Local Gauge Group

Wei-Min Sun, Xiang-Song Chen, Fan Wang

We evaluated some particular type of functional integral over the local gauge group C^{\infty}({\bf R}^n, U(1)) by going to a discretized lattice. The results explicitly violates t…
