Composite electric S-brane solutions with maximal number of branes and several scalar fields

A (n+1)-dimensional cosmological model with a set of scalar fields and antisymmetric (p+2)-form is considered. Some of scalar fields may have negative kinetic terms, i.e. they may describe “phantom” fields. For certain odd dimensions (D = 4m + 1 = 5, 9, 13, ...) and (p + 2)forms (p = 2m−1 = 1, 3, 5, ...) and non-exceptional dilatonic coupling vector ~λ we obtain cosmological-type solutions to the field equations. These solutions are characterized by self-dual or anti-self-dual charge density forms Q (of rank 2m) and may describe the maximal set of branes (i.e. when all the branes have non-zero charge densities). Some properties of these solutions are considered, e.g. Kasner-like behavior, the existence of non-singular (e.g. bouncing) solutions and those with acceleration. The solutions with bouncing and acceleration take place when at least there is one “phantom” field in the model. [email protected] [email protected] [email protected]
