DBI analog of a decaying vacuum cosmology

Understand

In this work I discuss the dynamical and thermodynamical equivalence between a general k-essence scalar field cosmology and an arbitrary cosmological model with a decaying vacuum, thus generalizing the approach proposed by Maia and Lima [Phys.

• The formalism obtained is quite general and holds for any non-canonical scalar field model.
