Over recent decades, the role of torsion in gravity has been extensively investigated along
the main direction of bringing gravity closer to its gauge formulation and incorporating spin …

We review many quantum aspects of torsion theory and discuss the possibility of the space–
time torsion to exist and to be detected. The paper starts, in Section 2, with a pedagogical …

We show that the f (T) gravitational paradigm, in which gravity is described by an arbitrary
function of the torsion scalar, can provide a mechanism for realizing bouncing cosmologies …

In part one of Effective Action in Quantum Gravity, the book describes the principles of
quantum field theory and the significance of and theory behind effective action. Part two …

Spectral functions relevant in the context of quantum field theory under the influence of
spherically symmetric external conditions are analysed. Examples comprise heat-kernels …

Theoretical and experimental research on general relativity with torsion is reviewed. An
introductory section establishes definitions and notation, introduces tetrads, the …

The Einstein static (ES) universe has played a major role in various emergent scenarios
recently proposed in order to cure the problem of the initial singularity of the standard model …

We present a brief, and to a great extent, pedagogical, review on renormalization in curved
spacetime and some recent results on the derivation and better understanding of quantum …

Torsion appears in literature in quite different forms. Generally, spin is considered to be the
source of torsion, but there are several other possibilities in which torsion emerges in …

A bstract Gravity and general relativity are considered as an Effective Field Theory (EFT) at
low energies and macroscopic distances. The effective action of the conformal anomaly of …
