I am studying about Drinfeld Modules for my Master's thesis,but I have not yet learnt about schemes and algebraic geometry.The set-up for Drinfeld modules,according to Goss' Basic structures of Function Field Arithmetic says that we first start with a smooth projective geometrically connected curve over a finite field $F_r$?
I've hunted high and low googling for a definition,but all I couldn't find anything.
If anyone could help ,I'd be very grateful
