|TITLE||Geometric maximal functions associated with spheres|
|ABSTRACT||This talk will be about maximal operators associated with a family of spheres, which include the
classical spherical maximal function as a special case. We will study properties of sets, such as the
Lebesgue measure and the Hausdorff dimension, containing a family of spheres which may be regarded
as Nikodym sets for spheres. This talk will be based on a joint work with Alan Chang and Georgios Dosidis.
