particular, we take into account extended metric, teleparallel and symmetric-teleparallel …

From the Weyl-Schrödinger connection to the accelerating Universe: Extending Einstein's gravity via a length preserving nonmetricity

L Ming, SD Liang, HH Zhang, T Harko - Physical Review D, 2024 - APS
One of the important extensions of Riemann geometry is Weyl geometry, which is essentially
based on the ideas of conformal invariance and nonmetricity. A similar non-Riemannian …

Cosmological constraints on a dynamical dark energy model in F(Q) gravity

O Enkhili, S Dahmani, D Mhamdi, T Ouali… - The European Physical …, 2024 - Springer
Extended teleparallel gravity, characterized by function F (Q), where Q is the non-metricity
scalar, is one of the most promising approaches to general relativity. In this paper, we …
