 ">Growth of quadratic forms under Anosov subgroups</a>\nby Leon Carvajales
  (Université de Paris-Sorbonne Université) as part of Pangolin seminar\n
 \n\nAbstract\nFor positive integers p and q we define a counting problem i
 n the (pseudo-Riemannian symmetric) space of quadratic forms of signature 
 (p\,q) on R^{p+q}. This is done by associating to each quadratic form a ge
 odesic copy of the Riemannian symmetric space of PSO(p\,q) inside the Riem
 annian symmetric space of PSL_{p+q}(R)\, and by looking at the orbit of th
 is geodesic copy under the action of a discrete subgroup of PSL_{p+q}(R). 
 We then present some contributions to the study of this counting problem f
 or Borel-Anosov subgroups of PSL_{p+q}(R).\n
