Dynamical analysis of the covariant gravity models
S. A. Narawade, S. A. Kadam
In this study, we explore the cosmological evolution of the Universe in the framework of covariant gravity, with a coupling function that evolves dynamically in proportion t…
Observational tests of \texorpdfstring{}{Lambda(t)} cosmology in light of DESI DR2
D. Revanth Kumar, Santosh Kumar Yadav, S. A. Kadam
In this article, we investigate two phenomenological decaying vacuum cosmological models describing the accelerated expansion of the Universe. We constrain the model parameters usi…
Cosmological Parameters in Gravity: Theoretical and Observational Analysis
Suraj Kumar Behera, S. A. Kadam, Pratik P. Ray +1
The gravity is one of the extensions of teleparallel equivalent of general relativity, in which more general functions of the torsion scalar can be described. With the p…
Dynamical Evolution in Generalized Scalar-Torsion Gravity with Extended Couplings
S. A. Kadam
In this study we explore the cosmological behavior of a non-minimally coupled scalar field that is linked to torsion gravity. We demonstrate the Sorkin-Schutz formalism with genera…
Dynamical and Cosmological Aspects of Teleparallel and Extended Teleparallel Gravity
S. A. Kadam
This thesis investigates modified teleparallel gravity models with a scalar field and teleparallel boundary terms, focusing on their cosmological implications for late-time cosmic…
Teleparallel Gravity and Quintessence: The Role of Nonminimal Boundary Couplings
S. A. Kadam, L. K. Duchaniya, B. Mishra
In this paper, we have outlined the development of an autonomous dynamical system within a general scalar-tensor gravity framework. This framework encompasses the overall structure…
