Anisotropic Obstacle Problems for Minimal Surfaces: Regularity of the Free Boundary via the Cahn-Hoffman Transform
Ezequiel Barbosa, Rosivaldo Antonio Gonçalves, Luan de Figueiredo
We study an obstacle problem for surfaces minimizing an anisotropic surface energy of ellipsoidal type. Given a convex obstacle and a boundary datum, we seek a surface that minimiz…

Compactness for minimal surfaces with injectivity radius bounded from below
Luan de Figueiredo, Rosivaldo Gonçalves
We prove a compactness theorem for the space of closed embedded minimal surfaces with area bounded from above and injectivity radius bounded from below in a closed Riemannian -m…

Classification of Lie algebras constructed from via Derived Bracket
Luan Figueiredo
Derived brackets provide a mechanism for generating algebraic structures from graded Lie superalgebras, with applications in Poisson geometry, mathematical physics, and the theory…
