Abstract The Chern–Simons (CS) form evolved from an obstruction in mathematics into an
important object in theoretical physics. In fact, the presence of CS terms in physics is more …

A generalized version for the Rastall theory is proposed showing the agreement with the
cosmic accelerating expansion. In this regard, a coupling between geometry and the …

A bstract We classify and characterize fully all invertible anomalies and all allowed topo-
logical terms related to various Standard Models (SM), Grand Unified Theories (GUT), and …

This is intended as a broad introduction to Chern-Simons gravity and supergravity. The
motivation for these theories lies in the desire to have a gauge invariant system--with a fiber …

The most general theory of gravity with torsion in D dimensions is discussed. The
Lagrangian is required to be:(i) a D-form scalar under local Lorentz transformations;(ii) a …

'The authors provide an up-to-date, well-organised background and essential elements of
supergravity notions as well as all relevant aspects of Chern-Simons forms in gravitation …

We present covariant gravitational equations to describe a four-dimensional brane world in
the case with a Gauss-Bonnet term in a bulk spacetime, assuming that gravity is confined on …

Motivated by gauge/gravity group in the low energy effective theory of the heterotic string
theory and novel aspects of massive gravity in the context of lattice physics, the minimal …

We consider brane world scenarios including the leading correction to the Einstein-Hilbert
action suggested by superstring theory, the Gauss-Bonnet term. We obtain and study the …

The gravitational deflection of light is a common effect for the massive objects in galactic
astronomy. Recently, several universal models with Finsler background were introduced to …
