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…
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…
The geometry of a Randers rotational surface with an arbitrary direction wind
Rattanasak Hama, Sorin V. Sabau
In the present paper we study the global behaviour of geodesics on a Randers metric, defined on a topological cylinder, obtained as the solution of the Zermelo's navigation problem…
The cut locus of a Randers rotational 2-sphere of revolution
Rattanasak Hama, Jaipong Kasemsuwan, Sorin V. Sabau
In the present paper we study the structure of the cut locus of a Randers rotational 2-sphere of revolution . We show that in the case when the Gaussian curvature of…
