On the first width of hyperbolic surfaces: multiplicity and lower bounds
Vanderson Lima
On a closed Riemannian surface of negative curvature, we prove a characterization for configurations of closed geodesics arising from one parameter Allen-Cahn min-max constructions…

Eigenvalue problems and free boundary minimal surfaces in spherical caps
Vanderson Lima, Ana Menezes
Given a compact surface with boundary, we introduce a family of functionals on the space of its Riemannian metrics, defined via eigenvalues of a Steklov-type problem. We prove that…

A two-piece property for free boundary minimal hypersurfaces in the -dimensional ball
Vanderson Lima, Ana Menezes
We prove that every hyperplane passing through the origin in $\rr^{n+1}$ divides an embedded compact free boundary minimal hypersurface of the euclidean -ball in exactly two…
