Multicomponent perfect fluid with variable parameters in n Ricci-flat spaces
J. -M. Alimi, V. R. Gavrilov, V. N. Melnikov
D-dimensional cosmological model describing the evolution of a multicomponent perfect fluid with variable barotropic parameters in n Ricci-flat spaces is investigated. The equation…
Friedmann universe with dust and scalar field
V. R. Gavrilov, V. N. Melnikov, S. T. Abdyrakhmanov
We study a spatially flat Friedmann model containing a pressureless perfect fluid (dust) and a scalar field with an unbounded from below potential of the form $V(\fii)=W_0 - V_0\si…
General solutions for flat Friedmann universe filled by perfect fluid and scalar field with exponential potential
H. Dehnen, V. R. Gavrilov, V. N. Melnikov
We study integrability by quadrature of a spatially flat Friedmann model containing both a minimally coupled scalar field with an exponential potential $V(ϕ)\sim\exp[-\sqrt{6}σ…
X-fluid and viscous fluid in D-dimensional anisotropic integrable cosmology
V. R. Gavrilov, V. N. Melnikov
D-dimensional cosmological model describing the evolution of a perfect fluid with negative pressure (x-fluid) and a fluid possessing both shear and bulk viscosity in n Ricci-flat s…
Exact Solutions in Multidimensional Cosmology with Shear and Bulk Viscosity
V. R. Gavrilov, V. N. Melnikov, Roland Triay
Multidimensional cosmological model describing the evolution of a fluid with shear and bulk viscosity in Ricci-flat spaces is investigated. The barotropic equation of state for…
Integrable spherically symmetric p-brane models associated with Lie algebras
S. Cotsakis, V. R. Gavrilov, V. N. Melnikov
A classical model of gravity theory with several dilatonic scalar fields and differential forms admitting an interpretation in terms of intersecting p-branes is studied in (pseudo)…
