    Course description:

    From blurb: ``Modular forms involve a wonderful overlap of arithmetic, algebra, analysis and geometry. This is a basic course on modular forms, expected to take an analytic viewpoint
    but covering algebraic aspects. It will cover the modular group, classical modular forms (holomorphic and non-holomorphic) Eisenstein series, and may cover related spectral theory
    for SL(2, R). This will include Hecke operators and the connection with Dirichlet series with Euler products. It will also cover various aspects of theta functions, quadratic forms
    and associated theory. Applications may include theory of partitions, representations by quadratic forms, connections to elliptic curves, with and without complex multiplication."


    Math 575/675 is helpfu1.
    Some comfort with complex analysis is helpful.


    Grades: These will be based on problem sets. There will be approximately 7 or 8 problem sets.

    Collaboration on the homework is permitted, but each person is responsible for writing up her/his own solutions. All external sources used in getting solutions should be explicitly credited, individually or at end of homework.
