Multiwormholes and multi-black-holes in three dimensions

Relating black holes in two and three dimensions.

The three dimensional black hole solutions of Bañados, Teitelboim and Zanelli (BTZ) are dimensionally reduced in various different ways. Solutions are obtained to the JackiwTeitelboim theory of two dimensional gravity for spinless BTZ black holes, and to a simple extension with a non-zero dilaton potential for black holes of fixed spin. Similar reductions are given for charged black holes. The ...

Geometry of Black Holes and Multi-Black-Holes in 2+1 dimensions

Black Holes in Higher Dimensions

We review black-hole solutions of higher-dimensional vacuum gravity and higher-dimensional supergravity theories. The discussion of vacuum gravity is pedagogical, with detailed reviews of Myers-Perry solutions, black rings, and solution-generating techniques. We discuss black-hole solutions of maximal supergravity theories, including black holes in anti-de Sitter space. General results and open...

Black Holes in Two Dimensions

Models of black holes in (1 + 1)-dimensions provide a theoretical laboratory for the study of semi-classical e ects of realistic black holes in Einstein's theory. Important examples of two-dimensional models are given by string theory motivated dilaton gravity, by ordinary general relativity in the case of spherical symmetry, and by Poincar e gauge gravity in two spacetime dimensions. In this p...

Non-abelian black holes and black strings in higher dimensions

We review the properties of static, higher dimensional black hole solutions in theories where non-abelian gauge fields are minimally coupled to gravity. It is shown that black holes with hyperspherically symmetric horizon topology do not exist in d > 4, but that hyperspherically symmetric black holes can be constructed numerically in generalized Einstein-Yang-Mills models. 5dimensional black st...
