摘要:Let A be a polynomial ring over a finite field and k its fraction field. Given a Drinfeld modular form f with algebraic “Fourier” coefficients, we consider n different CM points so that f is non-vanishing at these points. We prove a sufficient and necessary condition (in terms of the CM points) for the special values of f at these CM points to be algebraically independent over k.
