We present a review of gravitating particle-like and black hole solutions with non-Abelian
gauge fields. The emphasis is given to the description of the structure of the solutions and to …

We review the attempts to construct unified theories defined in higher dimensions which are
dimensionally reduced over coset spaces. We employ the coset space dimensional …

Higher-dimensional Kaluza-Klein theories with extra compactified time-like variables are
considered. Topological criteria are presented for a compact manifold which prevent the …

A bstract We investigate the twelve-dimensional gauge-Higgs unification models with an
eight-dimensional coset space as the extra space. For each model, we apply the coset …

Abstract We study multidimensional Einstein-Yang-Mills cosmologies. The stability of the
compactifying solutions in the radiation-dominated period that followed the inflationary …

We consider the discrete symmetries of all the six-dimensional coset spaces and we apply
them in gauge theories defined in ten dimensions which are dimensionally reduced over …

We investigate the gauge-Higgs unification models within the scheme of the coset space
dimensional reduction, beginning with a gauge theory in a fourteen-dimensional spacetime …

We examine the virtues and difficulties of the attempts to construct realistic four-dimensional
models from a gauge theory based on E 8 and defined in ten dimensions. The four …

We investigate the twelve-dimensional gauge-Higgs unification models with an eight-
dimensional coset space. For each model, we apply the coset space dimensional reduction …

A connection between dimensional reduction and spontaneous compactification is studied.
It is shown that the methods of the coset-space dimensional-reduction scheme can be …
