# Metric-Affine Cosmologies: Kinematics of Perfect (Ideal) Cosmological Hyperfluids and First Integrals

@inproceedings{Iosifidis2023MetricAffineCK, title={Metric-Affine Cosmologies: Kinematics of Perfect (Ideal) Cosmological Hyperfluids and First Integrals}, author={Damianos Iosifidis}, year={2023} }

We consider a generic Metric-Aﬃne Cosmological setup and classify some particularly interesting speciﬁc cases of Perfect Hyperﬂuids. In particular, we present the form of conservation laws for the cases of pure spin, pure dilation and pure shear ﬂuids. We also develop the concept of an incompressible hyperﬂuid and pay special attention to the case of a hypermomentum preserving hyperﬂuid. We also give a speciﬁc example on the emergence of the spin, dilation and shear currents through matter…
