Noether symmetry in gravity with -essence
arXiv:1601.07357
Abstract
In gravity theory, a Friedman-Robertson-Walker cosmological model with -essence where fermion field is non-minimally coupled with the gravitational field is studied. Using the Noether symmetry approach the possible forms of gravity and the non-canonical fermionic lagrangian are determined. Cosmological solutions of the condered models describing the accelerated and decelerated periods of the universe are found.
