Effective dissipative cosmology with from the first law of thermodynamics
Nobuyoshi Komatsu
We phenomenologically derive a cosmological model that includes both a cosmological constant term and a dissipative driving term by applying both the f…

Cosmological scenario based on the first and second laws of thermodynamics: Thermodynamic constraints on a generalized cosmological model
Nobuyoshi Komatsu
The first and second laws of thermodynamics should lead to a consistent scenario for discussing the cosmological constant problem. In the present study, to establish such a thermod…

Holographic thermodynamic relation for dissipative and non-dissipative universes in a flat FLRW cosmology
Nobuyoshi Komatsu
To clarify a holographic modified thermodynamic relation, the present study applies a general formulation for cosmological equations in a flat FLRW universe to the first law of the…
