Soap bubbles and isoperimetric regions in the product of a closed manifold with Euclidean space
Jesús Gonzalo Pérez
For any closed Riemannian manifold we prove that large isoperimetric regions in are of the form (Euclidean ball). We prove that if has non-n…

Generalised spin structures on 2-dimensional orbifolds
Hansjörg Geiges, Jesús Gonzalo
Generalised spin structures, or r-spin structures, on a 2-dimensional orbifold Σare r-fold fibrewise connected coverings (also called r-th roots) of its unit tangent bundle STΣ. We…

Contact spheres and hyperkähler geometry
Hansjörg Geiges, Jesús Gonzalo
A taut contact sphere on a 3-manifold is a linear 2-sphere of contact forms, all defining the same volume form. In the present paper we completely determine the moduli of taut cont…
