Some Problems Concerning Interchange of Order of Integration in Functional Integral Formalism of U(1) Gauge Field Theories

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

We show that in the functional integral formalism of U(1) gauge field theory some formal manipulation such as interchange of order of integration can yield erroneous results. The e…

Difficulties in a Kind of Averaging Procedure for Constructing Gauge-invariant Operators out of Gauge-variant Ones

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

We prove that a kind of averaging procedure for constructing gauge-invariant operators(or functionals) out of gauge-variant ones is erroneous and inapplicable for a large class of…
