Equivalence between the Descriptions of Cosmological Models Using a Spinor Field and a Perfect Fluid

A possibility of simulating a perfect fluid using spinor fields with different nonlinearities is investigated. Exact cosmological solutions to Einstein's equations with spinor fields are compared to the corresponding ones with perfect fluids.
