Abstract
A systematic study of properties of -number Schwinger terms in the algebra of currents is carried out on the basis of Lorentz covariance. It is found that these terms can be expressed by means of a second-rank Lorentz tensor. As an application, the existence of a covariant time-ordered product of two currents is proven for a wide class of Schwinger terms.
