Towards a unified Lagrangian formalism for Cosmology and Black Holes
G. Avila, J. A. Nieto
Using a Lagrangian formalism we establish a relationship between the (n + D + d) dimensional cosmology, black-holes and the Polyakov action for strings. Specifically, we identify t…

Geometric Structure of Higher-Dimensional Spheres
G. Avila, S. J. Castillo, J. A. Nieto
We explain in some detail the geometric structure of spheres in any dimension. Our approach may be helpful for other homogeneous spaces (with other signatures) such as the de Sitte…

The Yamabe invariant for axially symmetric two Kerr black holes initial data
Gastón A. Avila, Sergio Dain
An explicit 3-dimensional Riemannian metric is constructed which can be interpreted as the (conformal) sum of two Kerr black holes with aligned angular momentum. When the separatio…
