Title: Algebraic hypergeometric functions
Abstract: I will discuss a characterization of the functions of the title (classical one-variable hypergeometric series that satisfy polynomial equation) in terms of the integrality of its Taylor coefficients. The proof relies on properties of the Hermitian form fixed by the monodromy group which, as it turns out, can be described by an ancient construction due to Bezout.
