i will present a vast generalization of taelman's 2012 celebrated class-number formula for drinfeld modules to the setting of (rigid analytic) l-functions of drinfeld module motives with galois equivariant coefficients. i will discuss applications and potential extensions of this formula to the category of t-modules and t-motives. this is based on joint work with ferrara, green and higgins, and a result of meetings in the ucsd drinfeld module seminar.
