Observational tests of the conformal osculating Barthel-Kropina cosmological model
Himanshu Chaudhary, Rattanasak Hama, Tiberiu Harko +2
We consider detailed cosmological tests of dark energy models obtained from the general conformal transformation of the Kropina metric, representing an -type Finslerian geom…
From Barthel Randers Kropina Geometries to the Accelerating Universe: A Brief Review of Recent Advances in Finslerian Cosmology
Amine Bouali, Himanshu Chaudhary, Lehel Csillag +4
We review recent developments in cosmological models based on Finsler geometry and extensions of general relativity within this framework. Finsler geometry generalizes Riemannian g…
Length-preserving biconnection gravity and its cosmological implications
Lehel Csillag, Rattanasak Hama, Mate Jozsa +2
We consider a length-preserving biconnection gravitational theory, inspired by information geometry, which extends general relativity by using the mutual curvature as the fundament…
Conformal gravitational theories in the Barthel-Kropina type Finslerian geometry, and their cosmological implications
Rattanasak Hama, Tiberiu Harko, Sorin V. Sabau
We consider dark energy models obtained from the general conformal transformation of the Kropina metric, representing an type Finslerian geometry, constructed as the ratio…
Cosmological tests of the osculating Barthel-Kropina dark energy model
Amine Bouali, Himanshu Chaudhary, Rattanasak Hama +3
We further investigate the dark energy model based on the Finsler geometry inspired osculating Barthel-Kropina cosmology. The Barthel-Kropina cosmological approach is based on the…
Dark energy and accelerating cosmological evolution from osculating Barthel-Kropina geometry
Rattanasak Hama, Tiberiu Harko, Sorin V. Sabau
Finsler geometry is an important extension of Riemann geometry, in which to each point of the spacetime manifold an arbitrary internal variable is associated. Interesting Finsler g…
Cosmological evolution and dark energy in osculating Barthel-Randers geometry
Rattanasak Hama, Tiberiu Harko, Sorin V. Sabau +1
We consider the cosmological evolution in an osculating point Barthel-Randers type geometry, in which to each point of the space-time manifold an arbitrary point vector field is as…
Jacobi stability analysis of scalar field models with minimal coupling to gravity in a cosmological background
Bogdan Dănilă, Tiberiu Harko, Man Kwong Mak +2
We perform the study of the stability of the cosmological scalar field models, by using the Jacobi stability analysis, or the Kosambi-Cartan-Chern (KCC) theory. In the KCC approach…
