"Does Entropy Focus?"

Aron Wall, IAS

ABSTRACT: In classical general relativity with positive energy matter,
nearby light rays are always focussed by matter.  This simple fact has
been used to prove many important results about black holes,
singularities, and other spacetimes.  I will describe how this focussing
result can be generalized to situations involving quantum fields, and also
to higher curvature gravity actions.
