  The finite-temperature behavior of gluon and of Faddeev-Popov-ghost
propagators is investigated for pure SU(2) Yang-Mills theory in Landau gauge.
We present nonperturbative results, obtained using lattice simulations and
Dyson-Schwinger equations. Possible limitations of these two approaches, such
as finite-volume effects and truncation artifacts, are extensively discussed.
Both methods suggest a very different temperature dependence for the magnetic
sector when compared to the electric one. In particular, a clear thermodynamic
transition seems to affect only the electric sector. These results imply in
particular the confinement of transverse gluons at all temperatures and they
can be understood inside the framework of the so-called Gribov-Zwanziger
scenario of confinement.
