DESCRIPTION:I will present the elementary nonperturbative method to obtain
  Green's functions (GFs) for timelike momenta based on Schwinger-Dyson equ
 ation framework. We assume there are no singularities in the second and th
 e fourth quadrants of the complex plane of space momentum components and p
 erform a multidimensional analogue of Wick rotation. This procedure define
 s Greens functions in a timelike Euclidean space. It will be shown that in
  the case of ladder QED2+1 the procedure is fully equivalent to the full M
 inkowski space solution. As another examples I will present the applicatio
 n for solution of SDE for the quark propagator in QCD in a two slightly di
 fferent approximation. The method and solution clarify the confinement of 
 quarks by generation of complex mass within confinement mechanism based on
  the lack of real poles at timelike momenta.\n\nhttps://indico.ific.uv.es/
