2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/96073In this talk I summarise recent results on the infrared exponents of SU($N_c$)-Yang-Mills theory. I discuss a self-consistent power law solution for the Dyson-Schwinger equations for general 1PI-Greens functions in the infrared. The corresponding running coupling has a fixed point at zero momentum, which turns out to be universal and gauge invariant within a class of transverse gauges. When calculated on a torus the infrared exponents of the ghost and gluon propagators differ from the corresponding continuum solutions. They agree, however, well with results from lattice calculations.6 pages, 3 figures, talk presented at Lattice2005(Topology and Confinement), Dublin, July 25-30, 2005. v2: reference addedHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
