Title: Old and new problems about spherical maximal functions

Date: Wednesday, Nov 1
Time: 11 a.m. - Noon
Room: Southwick 313

Abstract: We survey old and new problems and results on spherical means, regarding pointwise convergence, p-improving properties of local spherical maximal operators and consequences for sparse domination. We are especially interested in how the outcomes depend on suitable notions of fractal dimension of the dilation sets.
