The ten-parametric internal symmetry group is found in the D= 4 Einstein-Maxwell-dilaton-
axion theory restricted to space-times admitting a Killing vector field. The group includes …

A solution-generating technique is developed for D= 5 minimal supergravity with two
commuting Killing vectors based on the G 2 U-duality arising in the reduction of the theory to …

Stationary four-dimensional BPS solutions to gravity-coupled bosonic theories admitting a
three-dimensional σ-model representation on coset spaces are interpreted as null …

A new and surprisingly simple representation is found for the heterotic string bosonic
effective action in three dimensions in terms of complex potentials. The system is presented …

The gravity-coupled three-dimensional-model describing the stationary Einstein-Maxwell-
dilaton system with a general dilaton coupling constant is studied. The Killing equations for …

We study a bosonic four-dimensional effective action corresponding to the heterotic string
compactified on a six-torus (dilaton-axion gravity with one vector field) on a curved space …

We classify the spherically symmetric solutions of the Einstein-Maxwell dilaton field
equations in D dimensions and find some exact solutions of the string theory at all orders of …

In this paper, we study distorted, five-dimensional, electrically charged (nonextremal) black
holes on the example of a static and “axisymmetric” black hole distorted by external …

We derive and discuss black-hole solutions to the gravitating model in (2+ 1) dimensions.
Three different kinds of static black holes are found. One of these resembles the static BTZ …
