TL;DR
This paper presents a gauge-theoretical framework for describing motion in Poincaré Gauge Theory of gravity, using composite bundles to characterize reference frames, positions, and evolution, exemplified by orbital motion in Schwarzschild spacetime.
Contribution
It introduces a gauge-theoretical approach to motion in gravity theories, adapting the composite bundle interpretation for Poincaré Gauge Theory.
Findings
Successful formulation of orbital motion in Schwarzschild spacetime within the gauge framework
Characterization of reference frames and time evolution in gauge-theoretical terms
Provides a new perspective on motion in gauge theories of gravity
Abstract
A description of motion is proposed, adapted to the composite bundle interpretation of Poincar\'e Gauge Theory. Reference frames, relative positions and time evolution are characterized in gauge-theoretical terms. The approach is illustrated by an appropriate formulation of the familiar example of orbital motion induced by Schwarzschild spacetime.
