the speaker with Neshan Wickramasekera (Cambridge). The work develops a
regularity theory, with an associated compactness theorem, for weakly
defined hypersurfaces (codimension 1 integral varifolds) of a smooth Riemannian
manifold that are stationary and stable on their regular parts for volume
preserving ambient deformations. The main regularity theorem gives two
structural conditions on such a hypersurface that imply that, away from a
set of codimension 7 or higher, the hypersurface is locally either a
single smoothly embedded disk or precisely two smoothly embedded disks
intersecting tangentially. Easy examples show that neither structural
hypothesis can be relaxed. An important special case is when the varifold
corresponds to the boundary of a Caccioppoli set, in which case the structural
conditions can be considerably weakened.<span></span></span></i></p>
