The model of dark matter is presented where the dark matter is a classical gauge field. A spherical symmetric solution of Yang – Mills equation is obtained. The asymptotic behavior of the gauge fields and matter density ...

In the present work, we study the cosmological model with fermionic field and with the non-canonical kinetic term (f-essence). We present some important reductions of the model as well as some of its generalizations. We ...

This paper is devoted to the investigation of the modified Chaplygin gas model in the context of solvable kessence cosmologies. For this purpose, we construct equations of state parameter of this model for some ...
