ELECTRIC S-BRANE SOLUTIONS CORRESPONDING TO RANK-2 LIE ALGEBRAS: ACCELERATION AND SMALL VARIATION OF G
Gravitation and Cosmology. Том 14. 2008. С. 235-240
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.
