New Insight into the Relation between Torsion and Electromagnetism

TL;DR

This paper clarifies that the connection between torsion and electromagnetism is a formal consequence of geometric relations, challenging the idea that torsion trace directly represents electromagnetic potential.

Contribution

It demonstrates that the link between torsion trace and electromagnetism arises from geometric relations, not as a fundamental principle.

Findings

Torsion trace is not a fundamental electromagnetic potential.

The relation between torsion and electromagnetism is a geometric consequence.

Fibre bundle techniques reveal the underlying geometric structure.

Abstract

In several unified field theories the torsion trace is set equal to the electromagnetic potential. Using fibre bundle techniques we show that this is no leading principle but a formal consequence of another geometric relation between space-time and electromagentism.
