In physics, marginally outer trapped surfaces (MOTS) can be understood as quasi-local versions of black hole boundaries. Therefore, these surfaces are crucial to understand black holes and are widely used in black hole simulations. From a mathematical point of view, MOTS are prescribed mean curvature surfaces, that is a generalization of a minimal surface. I will talk about marginally outer trapped surfaces, introduce some of their properties, and explain the challenges when trying to construct them analytically.
