Generic autonomous system approach to interacting dark energy models
Parth Shah, Gauranga C. Samanta, Kazuharu Bamba +1
We explore an autonomous system analysis of dark energy models with interactions between dark energy and cold dark matter in a general systematic approach to cosmological fluids. W…
Stability analysis of f(Q) gravity models using dynamical systems
Pooja Vishwakarma, Parth Shah
In recent years, the modified theory of gravity known as gravity has drawn interest as a potential alternative to general relativity. According to this theory, the gravitati…
Cosmological dynamics of f(R) models in dynamical system analysis
Parth Shah, Gauranga C. Samanta
In this work we try to understand the late time acceleration of the universe by assuming some modification in the geometry of the space and using dynamical system analysis. This te…
Stability analysis for cosmological models in gravity using dynamical system analysis
Parth Shah, Gauranga C. Samanta
Modified gravity theories have received increased attention lately to understand the late time acceleration of the universe. This viewpoint essentially modifies the geometric compo…
Qualitative behavior of cosmological models combining various matter fields
Parth Shah, Gauranga C. Samanta, Salvatore Capozziello
The late time accelerated expansion of the universe can be realized using scalar fields with given self-interacting potentials. Here we consider a straightforward approach where a…
Kaluza-Klein bulk viscous fluid cosmological models and the validity of the second law of thermodynamics in gravity
G. C. Samanta, R. Myrzakulov, Parth Shah
The authors considered the bulk viscous fluid in gravity within the framework of Kaluza-Klein space time. The bulk viscous coefficient expressed as $ξ=ξ_0+ξ_1\frac{…
