Thermal properties of quantum electrodynamics in 2+1 dimensions and confinement

Thermal properties of quantum electrodynamics in 2+1 dimensions are studied. The systematic account for screening in the framework of skeleton perturbation theory removes the infrared divergencies of thermodynamic quantities which are related to the long-range interaction responsible for the confinement. This leads to non-analyticity of the type g2logg2. The polarisation tensor, the thermodynamic potential and the fermion self-energy are investigated and the results obtained are used to discuss the possible absence of deconfinement in the model under consideration
