In this paper, we investigate the newly developed f (R, T 2) theory (R is the Ricci scalar and T 2= T αβ T αβ, T αβ demonstrates the energy-momentum tensor) to explore some viable …
General teleparallel theories assume that curvature is vanishing in which case gravity can be solely represented by torsion and/or nonmetricity. Using differential form language, we …
This paper investigates the Noether symmetry approach in modified f (ℛ, φ, χ) theory of gravity, where ℛ is the Ricci scalar, φ is a scalar field and χ is the kinetic energy term. For …
Black holes play a crucial role in the understanding of the gravitational interaction. Through the direct observation of the shadow of a black hole by the event horizon telescope and the …
This volume summarizes the many alternatives and extensions to Einstein's General Theory of Relativity, and shows how symmetry principles can be applied to identify physically viable …

This paper explores exact cosmological solutions of anisotropic universe model through Noether symmetry technique in energy-momentum squared gravity. This theory resolves the …
We find exact solutions for f (T) teleparallel gravity for the cases of spherically and cylindrically symmetric tetrads. The adopted method is based on the search for Noether …
