Description

The stability of MOTS embedded in perfect fluid spacetimes is studied and an upper bound on the area of stable MOTS is obtained. Aspects of the topology of the MOTS, as well as the case when an extension is made to imperfect fluids, are discussed. and the ``growth" of certain matter and curvature quantities on stable MOTS are provided.
