| Abstract: | A new regularization operator, (e-ØL(X)ØR(X)/M2+e-ØR(X)ØL(X)/M2)|M→∞’ is proposed to calculate the variation of the fermion path-in-tegral measure under a chiral transformation, and the normal anomaly, i.e.Bardeen anomaly, is obtained .in this paper. Moreover, the non-Abelian anomaly of the cosec pure gauge fields is calcula-ted by means of this regularization operator.The corresponding results in Minkowski space can readily be obtained in the principal value integral. |
