Multidimensional Integrable Cosmological Models with Dynamical and Spontaneous Compactification
U. Bleyer, A. Zhuk
Multidimensional cosmological models with spaces of constant curvature are discussed classically and with respect to canonical quantization. These models are integrable…
Multidimensional Classical and Quantum Wormholes in Models with Cosmological Constant
U. Bleyer, V. D. Ivashchuk, V. N. Melnikov +1
A multidimensional cosmological model with space-time consisting of Einstein spaces is investigated in the presence of a cosmological constant and a homog…
Mass Bounds for Multidimensional Charged Dilatonic Black Holes
U. Bleyer, V. Ivashchuk
The multidimensional charged dilatonic black hole solution with internal Ricci-flat spaces is considered. The bound on the mass of the black hole is obtained. In the strong dil…
Resolution of simple singularities yielding particle symmetries in a space-time
M. Rainer
A finite subgroup of the conformal group SL(2,C) can be related to invariant polynomials on a hypersurface in C^3. The latter then carries a simple singularity, which resolves by a…
Stability and Hamiltonian formulation of higher derivative theories
Hans - Juergen Schmidt
We analyze the presumptions which lead to instabilities in theories of order higher than second. That type of fourth order gravity which leads to an inflationary (quasi de Sitter)…
Conformal Coupling and Invariance in Different Dimensions
M. Rainer
Conformal transformations of the following kinds are compared: (1) conformal coordinate transformations, (2) conformal transformations of Lagrangian models for a D-dimensional geom…
