Yuri N. Obukhov, Friedrich W. Hehl
TL;DR
This paper introduces a new variational theory for hyperfluids that resolves previous issues and offers a consistent classical matter source model within metric-affine gravity.
Contribution
It presents a novel variational framework for hyperfluids that eliminates supplementary condition problems in metric-affine gravity.
Findings
Developed a consistent hyperfluid model free of supplementary condition issues.
Provided a variational formulation suitable for metric-affine gravity.
Enhanced the theoretical understanding of classical matter sources in gravity theories.
Abstract
A new variational theory of a hyperfluid is constructed which is free of the supplementary condition issue and provides a consistent model of the classical matter source in the metric-affine gravity theory.
