Restricted Radon transforms and projections of planar sets

Classical Analysis and ODEs 2019-08-15 v1

Abstract

We establish a mixed norm estimate for the Radon transform in the plane when the set of directions has fractional dimension. This estimate is used to prove a result about an exceptional set of directions connected with projections of planar sets. That leads to a conjecture analogous to a well-known conjecture of Furstenberg.
