Exact solution of two-dimensional Palatini Gauss-Bonnet theory on a strip
Máximo Bañados, Marc Henneaux
We analyze the two-dimensional Palatini Gauss-Bonnet theory on an infinite strip (product of a finite interval with the infinite line, corresponding to ``time"). The theory has onl…

Spherical symmetric fields on torsion-free Palatini Gauss-Bonnet theory
Máximo Bañados, Daniela Bennett
The Gauss-Bonnet density `a la Palatini' is not a total derivative in four dimensions. We study spherically symmetric fields for the torsion-free theory. The resulting equations ar…

An exact five dimensional Weyl-Geometry Gauss-Bonnet Black Hole
Sebastian Bahamonde, Máximo Bañados
We present a new exact black hole solution of a 5-dimensional Weyl-geometry Gauss-Bonnet theory of gravity. The Euclidean sector defines a fully regular metric coupled to the Weyl…
