Abstract:
Infrared behaviour of the gauge-invariant spinor propagator is studied. It is proved that infrared singularities of such a propagator can be factored out in a form of the Wilson loop that includes only the slowly varying component of electromagnetic field and accumulates all the dependence of the initial Green function of the form of the path.
