Colour-Spin, Dilaton-Spin and Hypermomentum Perfect Fluids as the Sources of non-Riemannian Cosmologies
We consider the perfect fluid with intrinsic degrees of freedom, namely, the perfect colour-spin, dilaton-spin and hypermomentum fluids as the sources of the possible non-Riemannian spacetime structure. We develop the variational theories of the perfect fluids with intrinsic degrees of freedom on accounting the constraints in the Lagrangian density of the fluids with the help of Lagrange multipliers and taking into account the corresponding underlying geometrical structure. As a result we derive the expressions for the energy-momentum tensors. The consequences of the employing of these energy-momentum tensors to the development of early stage Universe models are investigated.
