Description

Infrared behaviour of an gauge-invariant spinor propagator is studied. It is proved that infrared singularities of such a propagator can be factorized out in a form of the Wilson loop that contains only slowly varying component of an electromagnetic field and accumulates all the dependence on the form of the patch of the initial Green function
