We propose a purely fermionic action with gauge and general relativistic invariances. This
implies a unified treatment of gravity and gauge theories without elementary metric tensor …

We briefly review the manifold incarnations and facets of the notion that gravity, in certain
regards, can be re-conceived as the product of two gauge theories. We begin with a short …

We develop a gauge theory of gravity on the basis of the principal fiber bundle over the four-
dimensional space-time M with the covering group P¯ 0 of the proper orthochronous …

We propose a general relativistic invariant theory in terms of only fundamental fermions
without any reference to a metric. The integration over matter quantum fluctuations …

Modern understanding of gravitational phenomena is based on the concept of the spacetime
geometry. This is drastically different from Newton's theory in which the Euclidean space and …

An introduction to gauge theories and the «New Physics» ADS Classic is now deprecated. It
will be completely retired in October 2019. This page will automatically redirect to the new ADS …

This work investigates alternative theories of gravity, the solutions to their field equations
and the constraints that can be imposed upon them from observation and experiment …

GR can be interpreted as a theory of evolving 3-geometries. A recent such formulation, the 3-
space approach of Barbour, Foster and Ó'Murchadha, also permits the construction of a …

We present theories of gravitation based, respectively, on the general linear group GL (n, R)
and its inhomogeneous extension IGL (n, R)[(SO (n− 1, 1) and [ISO (n− 1, 1) for torsion-free …

Classical gravity is understood as the geometry of spacetime, and it seems very different
from the other known interactions. In this review, I will instead stress the analogies: Like …
