SPEAKER:
Alan Chang, Princeton University
TITLE: Nikodym-type spherical maximal functions
ABSTRACT: We study L^p bounds on Nikodym maximal functions associated to spheres. In contrast to the spherical maximal functions studied by Stein and Bourgain, our maximal functions are uncentered: for each point in R^n, we take the supremum over a family of spheres containing that point.
A presto
