Galactic Entropy in Extended Kaluza-Klein Cosmology

Authors: Hilmi Yanar, Mustafa Salti, Oktay Aydogdu, Irfan Acikgoz, Erol Yasar

We use a Kaluza-Klein model with variable cosmological and gravitational terms to discuss the nature of galactic entropy function. For this purpose, we assume a universe filled with dark fluid and consider five-dimensional field equations using the Gamma law equation. We mainly discuss the validity of the first and generalized second laws of galactic thermodynamics for viable Kaluza-Klein models.
