On a model of an unconstrained hyperfluid
arXiv:gr-qc/0008014 · doi:10.1016/S0375-9601(96)80004-1
Abstract
A hyperfluid is a classical continuous medium carrying hypermomentum. We modify the earlier developed variational approach to a hyperfluid in such a way that the Frenkel type constraints imposed on the hypermomentum current are eliminated. The resulting self-consistent model is different from the Weyssenhoff type one. The essential point is a conservation of the hypermomentum current such that the final metrical and canonical energy-momentum forms coincide.
