Sigma-model Solutions and Intersecting p-Branes Related to Lie Algebras
M. A. Grebeniuk, V. D. Ivashchuk
A family of Majumdar-Papapetrou type solutions in sigma-model of p-brane origin is obtained for all direct sums of finite-dimensional simple Lie algebras. Several examples of p-bra…
Multidimensional Cosmology for Intersecting p-Branes with Static Internal Spaces
M. A. Grebeniuk, V. D. Ivashchuk, V. N. Melnikov
Multidimensional cosmological model with static internal spaces describing the evolution of an Einstein space of non-zero curvature and n internal spaces is considered. The action…
Composite p-branes on Product of Einstein Spaces
V. D. Ivashchuk
A multidimensional gravitational model with several scalar fields, fields of forms and cosmological constant is considered. When scalar fields are constant and composite p-brane mo…
On Symmetries of Target Space for Sigma-model of p-brane Origin
V. D. Ivashchuk
The target space M for the sigma-model appearing in theories with p-branes is considered. It is proved that M is a homogeneous space G/H. It is symmetric if and only if the U-vecto…
