2cocycles in current algebra
Abstract
A nontrivial extension of current algebra is investigated using the techniques of differential geometry. The condition for the extension is derived. It is shown that a nontrivial solution leads to field equations with the WessZuminoWitten anomaly. A simple application of the scheme to YangMills gauge theory is discussed also.
