Anisotropic Parabolic Obstacle Problems and the Stefan Problem: Regularity of the Evolving Free Boundary
Ezequiel Barbosa, Rosivaldo Gonçalves, Luan de Figueiredo
We study a parabolic obstacle problem for surfaces evolving by anisotropic mean curvature flow subject to an obstacle constraint. Given a convex obstacle and initial data, we seek…

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…

Operator on warped product manifolds
Ezequiel Barbosa, Mateus Souza, Celso Viana
In this work we studied the stability of the family of operators , , in a warped product of an infinite interval or real line by one compact manifold, whe…
