Abstract:   For a finite dimensional central division algebra over a number field or a local field, its period and index coincide. There are natural questions concerning bounding indices of division algebras of a given period over finitely generated fields. We shall explain how this question is related to bounding the dimensions of anisotropic quadratic forms over such fields and trace some progress concerning this question.
