  The method of the quantum kinetic equation is applied to the problem of
renormalization of the conductivity of normal metals by gauge electron-electron
interactions. It is shown that in the three-dimensional case the relativistic
electromagnetic interaction (vector interaction of electrons with transverse
photons) leads to an unusual temperature dependence, indicating a deviation
from the Fermi liquid theory at low temperatures. In two dimensions such
corrections are found to result from both the scalar (density-density or
Coulomb) and the vector (current-current) gauge interactions.
