A Short Course in Automorphic Functions draw portraitsThis concise three part treatment introduces undergraduate and graduate students to the theory of automorphic functions and discontinuous groups.

The necessary hyperbolic geometry is developed in the text. Chapter two develops automorphic functions and forms via the Poincar series. Formulas
