This article explores wormhole solutions within the framework of Finsler geometry and the modified gravity theory. Modifications in gravitational theories, such as f(R,T) gravity, propose alternatives that potentially avoid the exotic requirements. W

Abstract This study introduces a pioneering approach to analyzing compact stars through Finslerian geometry, which has not been previously explored in this context. By employing the Barthel connection within Finsler–Randers spaces, the research der

Abstract In this article, we investigate the charged gravastar under conformal motion with the background of Finsler geometry. Mazur and Mottola pioneered the concept of the gravastar (gravitational vacuum star) for the first time. This vacuum object

Abstract In this paper, we investigate the concept of cosmological constant-roll inflation within the framework of Finslerian space-time. We approach the theory of cosmic evolution using Finsler geometry, incorporating the parametrization of the anis

Abstract We disagree with the analysis presented in the paper entitled “Finslerian extension of an anisotropic strange star in the domain of modified gravity” (by Sourav Roy Chowdhury et al., published in Eur Phys J C 84:472, 2024). They applied

Abstract The main goal of this paper is to solve the Finslerian Kiselev black hole and investigate its thermodynamic characteristics surrounded by dust, radiation, quintessence, and the cosmological constant. Since these black holes have multiple hor

In this paper, we consider an inflation scenario in which the inflation roll rate, defined by [Formula: see text] is supposed to be constant and study constant-roll inflation by a scalar field with minimal coupling to gravity in the presence of non-c

In this paper, we study a class of Finsler metric in the form \(F=\alpha+\beta+\frac{2 \beta^{2}}{\alpha}-\frac{\beta^{4}}{3 \alpha^{3}}\) where \(\alpha= \sqrt{a_{i j} y^{i} y^{j}}\) is a Riemannian metric, \(\beta=b_{i} y^{i}\) is a 1−form. We ob
