- W2018602595 abstract "Using developed earlier our methods for multidimensional models cite{M1,M2,M3} a family of cosmological-type solutions in D-dimensional model with two sets of scalar fields vec{phi} and vec{psi} and exponential potential depending upon vec{phi} is considered. The solutions are defined on a product of n Ricci-flat spaces. The fields from vec{phi} have positive kinetic terms and vec{psi} are phantom fields with negative kinetic terms. For vector coupling constant obeying 0< vec{lambda}^2 < (D-1)/(D-2) a subclass of non-singular solutions is singled out. The solutions from this subclass are regular for all values of synchronous time tau in (- infty, + infty). For vec{lambda}^2 < 1/(D-2) we get an asymptotically accelerated and isotropic expansion for large values of tau." @default.
