ON METRIZABILITY OF INVARIANT AFFINE CONNECTIONS [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2012
The metrizability problem for a symmetric affine connection on a manifold, invariant with respect to a group of diffeomorphisms G, is considered. We say that the connection is G-metrizable, if it is expressible as the Levi-Civita connection of a G-invariant metric field. In this paper we analyze the G-metrizability equations for the rotation group G =

Schrödinger connection with selfdual nonmetricity vector in 2+1 dimensions

open access: yesPhysics Letters B, 2021
We present a three-dimensional metric affine theory of gravity whose field equations lead to a connection introduced by Schrödinger many decades ago.

Conformal Transformations in Metric-Affine Gravity and Ghosts [PDF]

open access: yes, 2012
Conformal transformations play a widespread role in gravity theories in regard to their cosmological and other implications. In the pure metric theory of gravity, conformal transformations change the frame to a new one wherein one obtains a conformal ...

Prolongations of affine connection and horizontal vectors

open access: yesДифференциальная геометрия многообразий фигур, 2020
The linear frame bundle over a smooth manifold is considered. The mapping dе defined by the differentials of the first-order frame e is a lift to the normal N, i.

Torsion Wave Solutions in Yang-Mielke Theory of Gravity

open access: yesAdvances in High Energy Physics, 2015
The approach of metric-affine gravity initially distinguishes it from Einstein’s general relativity. Using an independent affine connection produces a theory with 10 + 64 unknowns. We write down the Yang-Mills action for the affine connection and produce

Affine analogues of the Sasaki-Shchepetilov connection

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2016
For two-dimensional manifold M with locally symmetric connection ∇ and with ∇-parallel volume element vol one can construct a flat connection on the vector bundle TM⊕E, where E is a trivial bundle.

First Natural Connection on Riemannian Π-Manifolds

open access: yesMathematics, 2023
A natural connection with torsion is defined, and it is called the first natural connection on the Riemannian Π-manifold. Relations between the introduced connection and the Levi–Civita connection are obtained.

Linear and projective connections over a smooth manifold

open access: yesДифференциальная геометрия многообразий фигур, 2023
The principal bundles of the first order coframes and the second order coframes, as well as factor bundle of centroprojective (coaffine) coframes are considered.
