On Composite S-brane Solutions with Orthogonal Intersection Rules
نویسنده
چکیده
It is shown that non-composite intersecting S-brane solutions received recently by N. Ohta [Phys. Lett. B 558, 213 (2003); hep-th/0301095] are special case of cosmological-type solutions with composite p-branes obtained in our earlier publications. [email protected]

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. Th...
متن کاملPOST-NEWTONIAN PARAMETERS FOR GENERAL BLACK HOLE AND SPHERICALLY SYMMETRIC p-BRANE SOLUTIONS
Black hole p -brane solutions for a wide class of intersection rules are considered. The solutions are defined on a manifold which contains a product of (n − 1) Ricci-flat “internal” spaces. The post-Newtonian parameters β and γ corresponding to a 4-dimensional section of the metric for general intersection rules are studied. It is shown that β does not depend but γ depends on p -brane intersec...
متن کاملP-brane Black Holes and Post-Newtonian Approximation
We analyze p-brane black hole solutions with ‘block-orthogonal’ intersection rules. The post-Newtonian parameters β and γ corresponding to 4-dimensional section of the metric are calculated. A family of solutions with γ = 1 is singled out. Some examples of solutions (e.g. in D = 11 supergravity) are considered.

متن کاملFluxbrane and S-brane Solutions with Polynomials Related to Lie Algebras of Rank
Composite fluxbrane and S-brane solutions for a wide class of intersection rules are considered. These solutions are defined on a product manifold M1 × . . . × Mn which contains n Ricci-flat spaces M1, . . . ,Mn with 1-dimensional M1 . They are defined up to a set of functions obeying non-linear differential equations equivalent to Toda-type equations with certain boundary conditions imposed. E...
