DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUOR/41/">O
 n Bauschke-Bendit-Moursi modulus of averagedness</a>\nby Shawn Wang (UBC-O
  hosted) (UBC-Okanagan) as part of PIMS-CORDS SFU Operations Research Semi
 nar\n\nLecture held in ASB 10908.\n\nAbstract\nFirmly nonexpansive operato
 rs are important in Convex Analysis and Optimization and Algorithms. It is
  a special case of averaged operators. We classify averaged operators\, fi
 rmly nonexpansive operators\, and proximal mappings by\nthe BBW modulus of
  averagedness. One amazing result is that a proximal mapping of a convex f
 unction has its modulus of averagedness less than $1/2$ if and only if the
  function is Lipschitz smooth. Joint work with Shuang Song.\n
