  Results for three-point functions of Landau gauge Yang-Mills theory at
non-vanishing temperature are presented and compared to lattice results. It is
found that the three-gluon vertex is enhanced for temperatures below the phase
transition. At very low momenta it becomes negative for all temperatures.
Furthermore, truncation effects in functional equations are discussed at the
example of three-dimensional Yang-Mills theory for which a self-contained
solution is presented.
