Effects of weak self-interactions in a relativistic plasma on cosmological perturbations
H. Nachbagauer, A. K. Rebhan, D. J. Schwarz
The exact solutions for linear cosmological perturbations which have been obtained for collisionless relativistic matter within thermal field theory are extended to a self-interact…

Kinetic vs. Thermal-Field-Theory Approach to Cosmological Perturbations
Anton K. Rebhan, Dominik J. Schwarz
A closed set of equations for the evolution of linear perturbations of homogeneous, isotropic cosmological models can be obtained in various ways. The simplest approach is to assum…
