Description
Black holes stand as enigmatic phenomena within our universe, yet their precise definition presents a big challenge. The original definitions are only useful in static situations since they rely on global properties (we need to know the history of the whole universe to detect a black hole!). Marginally outer trapped surfaces (MOTS) were introduced in an effort to provide a quasilocal definition of a Black Hole. In recent years, they have turned out to be essential to studying certain aspects of the merger of black holes. In this talk, I will show how some classical tools from differential geometry and functional analysis can shed light on the relation between symmetry and stability of MOTS.
