Calculations are carried out in a covariant way. The results for i) and ii) are consistent with calculations by other authors using different frameworks, while our temperature-dependent correction to the electron magnetic moment (iii)) turns out to differ from the one previously evaluated. Ward-Takahashi identities are obtained and verified as a consistency proof.journal articlehttp://dx.doi.org/10.1007/BF01561124http://link.springer.commetadata only access53PhysicsParticles & FieldsFísica (Física)22 Física
