Abstract
Torsion arising from fermionic matter in the Einstein-Cartan formulation of general relativity is
considered in the context of Robertson-Walker geometries and the early Universe. An ambiguity
in the way torsion arising from hot fermionic matter in chiral models should be implemented is
highlighted and discussed. In one interpretation, chemical potentials in chiral models can contribute
to the Fkiedmann equation and give a negative contribution to the energy density.
