The standard Einstein-Maxwell equations in 2+1 spacetime dimensions, with a negative cosmological constant, admit a black hole solution. The 2+1 black hole -characterized by mass, angular momentumâ€¦ (More)

The geometry of the spinning black holes of standard Einstein theory in 2+1 dimensions, with a negative cosmological constant and without couplings to matter, is analyzed in detail. It is shown thatâ€¦ (More)

Static, spherically symmetric solutions of the field equations for a particular dimensional continuation of general relativity with negative cosmological constant are studied. The action is, in oddâ€¦ (More)

A new formula for the conserved charges in 3+1 gravity for spacetimes with local anti-de Sitter asymptotic geometry is proposed. It is shown that requiring the action to have an extremum for thisâ€¦ (More)

04.50.+h, 05.70.Ce, 97.60.Lf Typeset using REVTEX 1 The purpose of this note is to point out that the black-hole entropy may be derived in a simple manner if one regards the Euclidean Hilbert actionâ€¦ (More)

A three dimensional black hole solution of Einstein equations with negative cosmological constant coupled to a conformal scalar field is given. The solution is static, circularly symmetric,â€¦ (More)
