Samuel Lepe, Francisco Pe\~na, Joel Saavedra
TL;DR
This paper investigates how bulk brane viscosity influences Randall-Sundrum brane world cosmology with negative brane tension, using Eckart's theory to analyze the modifications to cosmological dynamics.
Contribution
It introduces the effect of bulk brane viscosity into the Randall-Sundrum model with negative tension, providing new insights into brane world cosmology.
Findings
Bulk viscosity alters the cosmological evolution on the brane.
Viscosity effects can modify the expansion rate of the universe.
The study offers a framework for including dissipative processes in brane cosmology.
Abstract
We study the effect of the inclusion of bulk brane viscosity on brane world (BW) cosmology in the framework of the Eckart's theory, we focus in the Randall-Sundrum model with negative tension on the brane.
