Generalized second law of thermodynamics in \(f(T)\) gravity with entropy corrections. (English) Zbl 1276.83048
Summary: We study the generalized second law (GSL) of thermodynamics in \(f(T)\) cosmology, where \(T\) is the torsion scalar in teleparallelism. We consider the universe as a closed bounded system filled with \(n\) component fluids in the thermal equilibrium with the cosmological boundary. We use two different cosmic horizons: the future event horizon and the apparent horizon. We show the conditions under which the GSL will be valid in specific scenarios of the quintessence and the phantom energy dominated eras. Further we associate two different entropies with the cosmological horizons: with a logarithmic correction term and a power-law correction term. We also find the conditions for the GSL to be satisfied or violated by imposing constraints on model parameters.

This reference list is based on information provided by the publisher or from digital mathematics libraries. Its items are heuristically matched to zbMATH identifiers and may contain data conversion errors. In some cases that data have been complemented/enhanced by data from zbMATH Open. This attempts to reflect the references listed in the original paper as accurately as possible without claiming completeness or a perfect matching.
