Involutions on sapphire Sol 3-manifolds and the Borsuk-Ulam theorem for maps into $R^{n}$

Alexandre Paiva Barreto, Daciberg Lima Gonçalves, Daniel Vendrúscolo

For each sapphire Sol $3$ -manifold, we classify the free involutions. For each triple $(M, τ; R^{n})$ where $M$ is a sapphire Sol $3$ -manifold and $τ$ is a free involution, we show i…

Deformation of Hyperbolic Cone-Structures: Study of the non-Colapsing case

Alexandre Paiva Barreto

This work is devoted to the study of deformations of hyperbolic cone structures under the assumption that the lengths of the singularity remain uniformly bounded over the deformati…
