چکیده
We construct 4-dimensional cosmological FRW–models by compactifying a black 5brane solution of type IIB supergravity, which carries both magnetic NS-NS-charge and RR-charge. The influence of nontrivial RR-fields on the dynamics of the cosmological models is investigated.

Kaluza-Klein black holes within heterotic string theory on a torus.
We point out that in heterotic string theory compactified on a 6-torus, after a consistent truncation of the 10-d gauge fields and the antisymmetric tensor fields, 4-dimensional black holes of Kaluza-Klein theory on a 6-torus constitute a subset of solutions. 04.50.+h,11.25Mj,11.17+y Typeset using REVTEX E-mail address: [email protected] E-mail address: [email protected]
متن کاملStrings from Flux Tube Solutions in Kaluza-Klein Theory
We calculate dimensional reduction of gravitational flux tube solutions in the scheme of Kaluza-Klein theory. The fifth dimension is compacified to a region of Planck size. Assuming the width of the tube to be also Planck size we obtain string-like object with physical fields originated from an initial 5D metric. The dynamics of these fields is inner one.
متن کاملDynamics of Multiple Kaluza - Klein Monopoles in M - and String Theory
We analyse the world-volume theory of multiple Kaluza-Klein monopoles in string and M-theory by identifying the appropriate zero modes of various fields. The results are consistent with supersymmetry, and all conjectured duality symmetries. In particular for M-theory and type IIA string theory, the low energy dynamics of N Kaluza-Klein monopoles is described by supersymmetric U(N) gauge theory,...
متن کاملKaluza-Klein black holes in string theory.
Exact solutions of heterotic string theory corresponding to four-dimensional magnetic black holes in N = 4 supergravity are described. The solutions describe the black holes in the throat limit, and consist of a tensor product of an SU(2) WZW orbifold with the linear dilaton vacuum, supersymmetrized to (1, 0) world sheet SUSY. One dimension of the SU(2) model is interpreted as a compactified fi...
متن کاملMatrix Membrane Big Bangs and D-brane Production
We construct Matrix Membrane theory in pp wave backgrounds that have a null linear dilaton in Type IIB string theory. Such backgrounds can serve as toy models of big bang cosmologies. At late times only abelian degrees of freedom survive, and if the Kaluza-Klein modes along one of the directions of the membrane decouple, standard perturbative strings emerge. Near the “big bang”, non-abelian con...
