Notes on "Quadratic Forms and Automorphic Forms" from the 2009 Arizona   Winter School
  These notes are an extension of the rough notes provided for my four lecture graduate level course on "Quadratic Forms and Automorphic Forms" at the March 2009 Arizona Winter School on Quadratic Forms. They are meant to give a survey of some aspects of the classical theory of quadratic forms over number fields and their rings of integers (e.g. over Q and Z), and their connection with modular and automorphic forms.
