DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDS/86/">The
  real orbits of complex Lagrangian Grassmannians</a>\nby Hyunmoon Kim (Uni
 versity of Toronto\, Tel Aviv University) as part of Geometry and Dynamics
  seminar\n\n\nAbstract\nThe Riemann sphere can be broken up into three orb
 its of SL(2\, R)\, as \ntwo open hemispheres and a great circle. We will d
 iscuss a generalization \nof this phenomenon in complex Lagrangian Grassma
 nnians of higher \ndimensions under the action of the real symplectic grou
 p. We will \ngive formulas for the number of orbits\, incidence relations\
 , and \ntheir dimensions. We will also show homotopy equivalences between 
 \nthese orbits and some other Grassmannian objects\, and if time permits\,
  \na strategy to compute their homology.\n
