DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NEDNT/42/">C
 lassification of divergence of trajectories</a>\nby Nattalie Tamam (Univer
 sity of Michigan) as part of New England Dynamics and Number Theory Semina
 r\n\nLecture held in Online.\n\nAbstract\nAs shown by Dani\, diophantine a
 pproximations are in direct correspondence to the behavior of orbits in ce
 rtain homogeneous spaces. We will discuss the interpretation of the diverg
 ent trajectories and the obvious ones\, the ones diverging due to a purely
  algebraic reason. As conjectured by Barak Weiss\, there is a complete cla
 ssification of divergent trajectories when considering the action of subgr
 oups of the diagonal group. We will discuss the last part of this conjectu
 re\, showing that for a ‘large enough’ such subgroup\, every divergent
  trajectory diverges obviously. This is a joint work with Omri Solan.\n
