چکیده
A family of generalized S-brane solutions with orthogonal intersection rules and n Ricci-flat factor spaces in the theory with several scalar fields and antisymmetric forms is considered. Two subclasses of solutions with power-law and exponential behaviour of scale factors are singled out. These subclasses contain sub-families of solutions with accelerated expansion of certain factor spaces. The solutions depend on charge densities of branes, their dimensions and intersections, dilatonic couplings and the number of dilatonic fields.

We construct generalized 11D supergravity solutions of fully localized D2/D6 brane intersections. These solutions are obtained by embedding Taub-NUT and/or self-dual geometries lifted to M-theory. We reduce these solutions to ten dimensions, obtaining new D-brane systems in type IIA supergravity. We discuss the limits in which the dynamics of the D2 brane decouples from the bulk for these solut...

Black hole generalized p-brane solutions for a wide class of intersection rules are obtained. The solutions are defined on a manifold that contains a product of n − 1 Ricci-flat " internal " spaces. They are defined up to a set of functions H s obeying a non-linear differential equations (equivalent to Toda-type equations) with certain boundary conditions. A conjecture on polynomial structure o...

Multidimensional gravitational model containing several dilatonic scalar fields and antisymmetric forms is considered. The manifold is chosen in the form M = M 0 × M 1 ×. .. × M n , where M i are Einstein spaces (i ≥ 1). When metric is block-diagonal, all fields and scale factors of the metric depend (essentially) on the point of M 0 and for the forms composite (electromagnetic) p-brane Ansatz ...

We extend the relation between instanton and monopole solutions of the selfduality equations in SU (2) gauge theory to noncommutative space-times. Using this approach we construct a noncommutative version of the Wu-Yang monopole satisfying the selfduality (Bogomol'nyi) equations in noncommutative U (2) Yang-Mills-Higgs theory.
