Three cocycles and the operator product expansion

Anomalous contributions to the Jacobi identity of chromoelectric fields and non-Abelian vector currents are calculated using a nonperturbative approach that combines operator product expansion and a generalization of the Bjorken-Johnson-Low limit. The failure of the Jacobi identity and the associated three-cocycles are discussed. {copyright} {ital 1997} {ital The American Physical Society}
