Classical automorphic forms and hypergeometric functions
The author exhibits a graded algebra of hypergeometric functions and shows how to canonically identify it with the graded algebra of modular forms for the full modular group SL(2,\({\mathbb{Z}})\). He also shows how Dedekind's eta-function is related to the square root of a hypergeometric function and gives yet another simple proof of its functional equation.
