Boltzmann equation in the -post-Newtonian approximation
Gilberto M. Kremer
Within the framework of the post-Newtonian approximation theory, a kinetic theory for relativistic gases in the presence of gravitational fields is developed. The Boltzm…

Fokker-Planck equation for the Brownian motion in the post-Newtonian approximation
Gilberto M. Kremer
A mixture of light-gas particles and Brownian heavy particles is analyzed within the framework of a post-Newtonian Boltzmann equation to determine the Fokker-Planck equation for th…

Slow-roll inflation from a geometric scalar-tensor model with self-interacting potentials
Abraão J. S. Capistrano, Gilberto M. Kremer
We consider slow-roll inflation in the context of a modified Brans-Dicke dilaton gravity. From a two self-interacting potentials , we reproduce a Starobinsky-like potential…
