In this work, we study cosmological spacetime configurations in f (Q) gravity with nonvanishing symmetric teleparallel connections. It is known that the spatially flat …

Symmetric teleparallel f (Q)-gravity allows for the presence of a perfect fluid with a tilted velocity in the Kantowski–Sachs geometry. In this dipole model, we consider an ideal gas …
We consider homogeneous and isotropic cosmological models in the framework of three geometrical theories of gravitation. In Einstein's general relativity, they are given in terms of …

In this article we confront a class of $ f (Q) $ gravity models with observational data of galaxy- galaxy lensing. Specifically, we consider the $ f (Q) $ gravity models containing a small …
We investigate the dynamics and the phase-space evolution for the scalar nonmetricity cosmology with a Chameleon mechanism. In particular, we consider a spatially flat …

We investigate the impact of conformal transformations on the physical properties of solution trajectories in nonmetricity gravity. Specifically, we explore the phase space and reconstruct …

Within the framework of symmetric teleparallel $ f\left (Q\right) $-gravity for a connection defined in the non-coincidence gauge we derive the Wheeler-DeWitt equation of quantum …
We solve the gravitational field equations for a static, spherically symmetric spacetime within the framework of the symmetric teleparallel theory of gravity. Specifically, we derive new …
