Gravitational Flux Tubes
V. Dzhunushaliev, U. Kasper, D. Singleton
By studying multidimensional Kaluza-Klein theories, or gravity plus U(1) or SU(2) gauge fields it is shown that these theories possess similar flux tube solutions. The gauge field…
Intersecting electric and magnetic p-branes: spherically symmetric solutions
K. A. Bronnikov, U. Kasper, M. Rainer
We consider a D-dimensional self-gravitating spherically symmetric configuration of a generalized electro-magnetic n-form F and a dilatonic scalar field, admitting an interpretatio…
Integrable Multicomponent Perfect Fluid Multidimensional Cosmology II: Scalar Fields
U. Kasper, M. Rainer, A. Zhuk
We consider anisotropic cosmological models with an universe of dimension 4 or more, factorized into n>1 Ricci-flat spaces, containing an m-component perfect fluid of m non-interac…
Stability Properties of the Starobinsky Cosmological Model
U. Kasper, S. Kluske, M. Rainer +2
We discuss the instabilities appearing in the cosmological model with a quasi de Sitter phase following from a fourth-order gravity theory. Both the classical equation as well as t…
