Myrzakulov Gravity in Vielbein Formalism: A Study in Weitzenböck Spacetime

Abstract: The quest to understand gravity's role in shaping the universe has led to the exploration of modified gravity theories. One such theory is Myrzakulov gravity, which incorporates both curvature and torsion. In this work, we investigate the effects of torsion within the framework of $f(R,T)$-gravity, a modification of General Relativity that includes both curvature and torsion. We present this theory in the Vielbein formalism, which offers a more flexible, geometric perspective on gravity. This formalism is particularly useful in Weitzenb"ock spacetime, where torsion significantly influences gravitational interactions. Our study aims to extend Myrzakulov's theory and explore its cosmological and astrophysical implications. We examine the effects of torsion on phenomena like black holes, gravitational waves, and neutron stars. These modifications could lead to observable deviations in black hole thermodynamics, gravitational wave propagation, and dense matter structure. This work provides new insights into the nature of spacetime and gravity, offering a fresh perspective on the fundamental forces governing the cosmos. It paves the way for future studies, both observational and theoretical, that could reveal new physics beyond General Relativity.
