Query: Hyperbolic monodromy groups for the hypergeometric equation and Cartan
  involutions   We give a criterion which ensures that a group generated by Cartan
involutions in the automorph group of a rational quadratic form of signature
(n-1,1) is "thin", namely it is of infinite index in the latter. It is based on
a graph defined on the integral Cartan root vectors, as well as Vinberg's
theory of hyperbolic reflection groups. The criterion is shown to be robust for
showing that many hyperbolic hypergeometric groups for n_F_(n-1) are thin.
