The Green's Causal Functions of Bilocal Fields

On concrete examples it is demonstrated that in quantum field theory with three universal constants c, h, and k suggested in 1], the limiting value k ^–1 = 0 corresponding to local theory is a bifurcation point: the Green's causal function for finite k bifurcates into . The natural carrier of the latter is the Euclidean space-time R ₄, and its continuation from R ₄ to R _3,1 is regular. The former is singular at zero point and on the light cone and hence is rejected.
