Weakly almost-Fuchsian manifolds are nearly-Fuchsian

Manh-Tien Nguyen, Jean-Marc Schlenker, Andrea Seppi

We show that a hyperbolic three-manifold containing a closed minimal surface with principal curvatures in also contains nearby (non-minimal) surfaces with principal cu…

Uniqueness and non-uniqueness for the asymptotic Plateau problem in hyperbolic space

Zheng Huang, Ben Lowe, Andrea Seppi

We prove several results on the number of solutions to the asymptotic Plateau problem in . Firstly we discuss criteria that ensure uniqueness. Given a Jordan curve …

Quasi-Fuchsian manifolds close to the Fuchsian locus are foliated by constant mean curvature surfaces

Diptaishik Choudhury, Filippo Mazzoli, Andrea Seppi

Even though it is known that there exist quasi-Fuchsian hyperbolic three-manifolds that do not admit any monotone foliation by constant mean curvature (CMC) surfaces, a conjecture…

Hypersurfaces of constant Gauss-Kronecker curvature with Li-normalization in affine space

Xin Nie, Andrea Seppi

For convex hypersurfaces in the affine space (), A.-M.\ Li introduced the notion of -normal field as a generalization of the affine normal field. By s…
