Metrizability of -invariant connections: Riemann versus Finsler

N Voicu, SG Elgendi - Classical and Quantum Gravity, 2024 - iopscience.iop.org
For a torsion-free affine connection on a given manifold, which does not necessarily arise as
the Levi–Civita connection of any pseudo-Riemannian metric, it is still possible that it …

In this paper, using the Finslerian settings, we study the existence of parallel one forms (or,
equivalently parallel vector fields) on a Riemannian manifold. We show that a parallel one …
