摘要: In the present work, we study cosmological model with fermionic field and non-canonical kinetic term (f-essence). We also some important reductions of as well its generalizations. found exact solution examine influence such gravity-fermion interaction on observed accelerated expansion our universe. Several bosonic-fermionic DBI models were constructed particular f-essence g-essence, respectively their Chaplygin gas counterparts are found. Finally, nonlinear bouncing cyclic universes proposed.
