Billiard representation for multidimensional multi-scalar cosmological model with exponential potentials
H. Dehnen, V. D. Ivashchuk, V. N. Melnikov
Multidimensional cosmological-type model with n Einstein factor spaces in the theory with l scalar fields and multiple exponential potential is considered. The dynamics of the mode…
On exact solutions in multidimensional gravity with antisymmetric forms
V. D. Ivashchuk
This short review deals with a multidimensional gravitational model containing dilatonic scalar fields and antisymmetric forms. The manifold is chosen in the product form. The sigm…
On spherically symmetric solutions with horizon in model with multicomponent anisotropic fluid
H. Dehnen, V. D. Ivashchuk
A family of spherically symmetric solutions in the model with m-component anisotropic fluid is considered. The metric of the solution depends on parameters q_s, s = 1,...,m, relati…
Cosmological solutions in multidimensional model with multiple exponential potential
V. D. Ivashchuk, V. N. Melnikov, A. B. Selivanov
A family of cosmological solutions with Ricci-flat spaces in the theory with several scalar fields and multiple exponential potential is obtained when coupling vectors in e…
On composite S-brane solutions with orthogonal intersection rules
V. D. Ivashchuk
It is shown that non-composite intersecting S-brane solutions received in hep-th/0301095 are special case of cosmological-type solutions with composite p-branes obtained in our ear…
Generalized pp-wave solutions on product of Ricci-flat spaces
V. D. Ivashchuk
A multidimensional gravitational model with several scalar fields and form fields is considered. A wide class of generalized pp-wave solutions defined on a product of n+1 Ricci-fla…
