Preferably some familiarity with MA 215 (Introduction to Modular Forms) but not necessary.

Holomorphic Modular forms: motivation and introduction, Eisentein series, cusp
forms, Fourier expansion of Poincare series and Petersson trace formula, Hecke
operators and overview of newform theory, Kloosterman sums and bounds for
Fourier coefficients, Automorphic L-functions, Dirichlet-twists and Weilâ€™s
converse theorm, Theta functions and representation by quadratic forms,
Convolution: the Rankin-Selberg method.
(Further topics if time permits: Non-holomorphic modular forms (overview),
Siegel modular forms (introduction), Elliptic curves and cusp forms, spectral
theory, analytic questions related to modular forms.)
