On metric-connection compatibility and the signature change of space-time [PDF]

, 1998
We discuss and investigate the problem of existence of metric-compatible linear connections for a given space-time metric which is, generally, assumed to be semi-pseudo-Riemannian.

Certain lie algebraic structures on Riemannian manifolds with semi-symmetric non-metric connection

Filomat, 2023
As a natural consequence of the Levi-Civita connection on a Riemannian manifold, there is a Lie algebra structure on a Riemannian manifold. Lie Algebras and Lie Groups are the mathematical structure of continuous symmetries in physics. In this paper, semi-symmetric non-metric connection is considered instead of Levi-Civita connection of ...

Leibnizian, Galilean and Newtonian structures of spacetime [PDF]

, 2002
The following three geometrical structures on a manifold are studied in detail: (1) Leibnizian: a non-vanishing 1-form $\Omega$ plus a Riemannian metric $\h$ on its annhilator vector bundle.
