DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OARS/1/">Max
 imal functions associated with a set of directions</a>\nby Jongchon Kim (U
 BC) as part of OARS Online Analysis Research Seminar\n\n\nAbstract\nThere 
 is a class of geometric problems in harmonic analysis associated with some
  curved manifolds such as the sphere or the paraboloid. In the study of th
 ese problems\, relevant geometric maximal functions play a central role. I
 n this talk\, we consider maximal averaging operators along line segments 
 oriented in a set of directions and their singular integral counterparts. 
 How do operator norms of these maximal functions depend on the number and 
 the distribution of directions? I will discuss some results in this direct
 ion and a divide-and-conquer approach for $L^2$ estimates.\n
