DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NEDNT/9/">Jo
 ining classification and factor rigidity in infinite volume</a>\nby Jacque
 line Warren (University of California\, San Diego) as part of New England 
 Dynamics and Number Theory Seminar\n\nLecture held in Online.\n\nAbstract\
 nFor a group acting on two spaces\, a joining of these systems is a measur
 e on the product space that is invariant under the diagonal action and pro
 jects to the original measures on each space. As an important step towards
  her celebrated measure classification theorem\, Ratner proved an early la
 ndmark result classifying joinings for horocycle flows on finite volume qu
 otients of PSL(2\,R). In this talk\, I will discuss joining classification
  for horospherical flows in the infinite volume\, rank one setting\, as we
 ll as a key factor rigidity theorem that is used in the proof.\n
