  We present non-perturbative correlation functions in Landau-gauge Yang-Mills
theory at finite temperature. The results are obtained from the functional
renormalisation group within a self-consistent approximation scheme. In
particular, we compute the magnetic and electric components of the gluon
propagator, and the three- and four-gluon vertices. We also show the ghost
propagator and the ghost-gluon vertex at finite temperature. Our results for
the propagators are confronted with lattice simulations and our Debye mass is
compared to hard thermal loop perturbation theory.
