black hole solutions
, 1998
"... We derive and discuss black–hole solutions to the gravitating O(3) σ model in (2+1) dimensions. Three different kinds of static black holes are found. One of these resembles the static BTZ black hole, another is completely free of singularities, and the last type has the same Penrose diagram as the ..."

We derive and discuss black–hole solutions to the gravitating O(3) σ model in (2+1) dimensions. Three different kinds of static black holes are found. One of these resembles the static BTZ black hole, another is completely free of singularities, and the last type has the same Penrose diagram
Black hole solutions in massive gravity
, 902
"... The static vacuum spherically symmetric solutions in massive gravity are obtained both analytically and numerically. The solutions depend on two parameters (integration constants): the mass M (or, equivalently, the Schwarzschild radius), and an additional parameter, the “scalar charge ” S. At zero v ..."

value of S and positive mass the standard Schwarzschild black hole solutions are recovered. Depending on the parameters of the model and the signs of M and S, the solutions may or may not have horizon. Those with the horizon describe modified black holes provided they are stable against small
Black Hole Solution of Quantum Gravity
, 2008
"... We present a spherically symmetric and static exact solution of Quantum Einstein Equations. This solution is asymptotically (for large r) identical with the black hole solution on the anti–De Sitter background and, for some range of values of the mass possesses two horizons. We investigate thermodyn ..."

Black Hole Solutions in String Theory
, 1994
"... We present twoparameter solutions of the lowenergy fourdimensional heterotic string which in the extremal limit reduce to supersymmetric monopole, string and domain wall solutions. The effective scalar coupling to the Maxwell field, e −αφ FµνF µν, gives rise to a new string black hole with α = √ ..."

A conformal scalar dyon black hole solution
, 1994
"... An exact solution of Einstein Maxwell conformal scalar field equations is given, which is a black hole solution and has three parameters: scalar charge, electric charge, and magnetic charge. Switching off the magnetic charge parameter yields the solution given by Bekenstein. In addition the energy ..."

Entropy of Extremal Black Hole Solutions of String Theory

"... For extremal black holes, the thermodynamic entropy is not proportional to the area. The general form allowed by thermodynamics is worked out for three classes of extremal black hole solutions of string theory and shown to be consistent with the entropy calculated from the density of elementary stri ..."

Static Black Hole Solutions With Axial Symmetry

On the smoothnes of the horizons of multiblack hole solution
 Phys. Rev
, 1995
"... In a recent paper it was suggested that some multiblack hole solutions in five or more dimensions have horizons that are not smooth. These black hole configurations are solutions to ddimensional Einstein gravity (with no dilaton) and are extremally charged with a magnetic type (d−2)form. In this ..."
