  • F -essence 
    P.Yu. Tsyba; G.N. Nugmanova (2012-06-27)
    In the present work, we study the cosmological model with fermionic field and with the non-canonical kinetic term (fermionic k-essence or f-essence ). We also present some important reductions of the model as well as its ...
  • Integrable Heisenberg Ferromagnet Equations with self-consistent potentials 
    Zh.Kh. Zhunussova; K.R. Yesmakhanova; D.I. Tungushbaeva; G.K. Mamyrbekova; G.N. Nugmanova; R. Myrzakulov (2013-04-19)
    In this paper, we consider some integrable Heisenberg Ferromagnet Equations with selfconsistent potentials. We study their Lax representations. In particular we give their equivalent counterparts which are nonlinear ...

  • Some cosmological aspects of Hoˇrava-Lifshitz gravity: integrable and nonintegrable models 
    G.N. Nugmanova; Sh.R. Myrzakul; O.V. Razina; K.R. Esmakhanova; N.S. Serikbayev; R. Myrzakulov (2012-09-20)
    In this work, some new integrable and nonintegrable cosmological models of the Hoˇrava- Lifshitz gravity are proposed. For some of them, exact solutions are presented. Then these results extend for the F(R) Hoˇrava-Lifshitz ...

  • Some Models of Cyclic and Knot Universes 
    K.R. Yesmakhanova; N. A. Myrzakulov; K. K. Yerzhanov; G.N. Nugmanova; N.S. Serikbayaev; R. Myrzakulov (2013-05-15)
    In this paper, we obtained a class of oscillatory, cyclic and knot type solutions from the non-linear Friedmann equations. This is performed by choosing specific forms of energy density and pressure of matter. All the ...
