Abstract
The dimensional regularization is applied to three-loop vacuum graphs in massless QED to evaluate temperature-dependent ultraviolet divergen ces and infrared divergences in arbitrary covariant gauge. They both a re shown to be absent due to cancellations among themselves, and the c ancellations are gauge-independent although the individual divergences are gauge-dependent.
