Dynamical system analysis of scalar field cosmology in coincident f (Q) gravity

S Ghosh, R Solanki, PK Sahoo - Physica Scripta, 2024 - iopscience.iop.org
In this article, we investigate scalar field cosmology in the coincident f (Q) gravity formalism.
We calculate the motion equations of f (Q) gravity under the flat Friedmann-Lemaître …

Phase space analysis and cosmography of a two-fluid cosmological model

G Mandal, SK Biswas - Physica Scripta, 2024 - iopscience.iop.org
In the framework of spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) space-time,
we investigate a two-fluid cosmological model where a tachyon scalar field with self …
