Growth of quadratic forms under Anosov subgroups
Leon Carvajales (Université de Paris-Sorbonne Université)
Abstract: For positive integers p and q we define a counting problem in 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 geodesic copy of the Riemannian symmetric space of PSO(p,q) inside the Riemannian symmetric space of PSL_{p+q}(R), and by looking at the orbit of this 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 for Borel-Anosov subgroups of PSL_{p+q}(R).
