Abstract: The progress in the last decade in perturbative quantum field theory at high temperatures and densities, made possible by the use of effective field theories and hard thermal/dense loop resummations in ultrarelativistic gauge theories, is reviewed. The relevant methods are discussed in field theoretical models from simple scalar theories to non-Abelian gauge theories including gravity. In the simpler models, the aim is to give a pedagogical account of some of the relevant problems and their resolution, while in the more complicated but also more interesting models such as quantum chromodynamics, a summary of the results obtained so far is given together with references to a few of the most recent developments and open problems.

Thermodynamics of the QCD Plasma and the Large-N Limit
TL;DR: The results for SU(N) Yang-Mills theories with N=3, 4, 5, 6, and 8 colors show a very mild dependence on N, supporting the idea that the QCD plasma could be described by models based on the large-N limit.
SU(N) gauge theories at large N
TL;DR: In this article, the authors review the theoretical developments and conceptual advances that stemmed from the generalization of QCD to the limit of a large number of color charges, originally proposed by ’t Hooft.

Perfect fluid theory and its extensions
TL;DR: In this paper, the authors review the canonical theory for perfect fluids in Euler's and Lagrange's formulations, which is related to a description of extended structures in higher dimensions, including internal symmetry and supersymmetry degrees of freedom.

Resummation in hot field theories
TL;DR: In this paper, the authors discuss the breakdown of naive perturbation theory at finite temperature and the need for an effective expansion that resums an infinite class of diagrams in the perturbative expansion.

TL;DR: In this article, the Hamiltonian formulation for non-Abelian gauge theory in two spatial dimensions is carried out in terms of a gauge-invariant matrix parametrization of the fields.
Propagators and dimensional reduction of hot SU(2) gauge theory
TL;DR: In this paper, the authors investigated the large distance behavior of the electric and magnetic propagators of hot SU(2) gauge theory in different gauges using lattice simulations of the full four-dimensional (4D) theory and the effective, dimensionally reduced, 3D theory.

TL;DR: In this article, it was shown that the retarded propagator of a massless fermion in hot QED plasmas behaves as S{sub R}(t{gt}1/gT]exp{l_brace}{minus}{alpha}Tt[ln{omega}{sub p}t+C]{r_brace}, where ρ is a constant, independent of g. This term is computed in this paper.
Transformations of real-time finite-temperature Feynman rules.
TL;DR: Trans transformations of the 2[times]2 propagator matrix in real-time finite-temperature field theory, resulting in transformed [ital n]-point functions are considered, and some aspects of these bases which arise in practical calculations are compared.
Effective theory for real-time dynamics in hot gauge theories
TL;DR: In this paper, the authors reformulated the hard thermal loop approximation as an effective classical thermal field theory for the soft modes, which is well suited for numerical studies of the non-perturbative dynamics in real time, in particular for the computation of the baryon number violation rate at high temperature.
