The aim of this research group is to advance work on the following ongoing projects:
1. Maximal operators of semigroups related to classical orthogonal expansions, the exotic index case (researchers: A. Nowak, P. Sjörgen, T. Z. Szarek)
2. Maximal operators of semigroups related to orthogonal expansions in multi-dimensional spheres and balls (researchers: P. Sjörgen, T.Z. Szarek)
3. Maximal operators related to non-doubling and non-radial measures (researchers: A. Nowak, E. Sasso, P. Sjörgen, K. Stempak)
