The Kakeya Needle Problem for Rectifiable Sets
Alan Chang (The University of Chicago)
Abstract:
We show that the classical results about rotating a line segment in arbitrarily small area, and the existence of a Besicovitch and a Nikodym set hold if we replace the line segment by an arbitrary rectifiable set. This is joint work with Marianna Csörnyei.
