Polynomial Functors of Modules
We introduce the notion of numerical functors to generalise Eilenberg &
MacLane's polynomial functors to modules over a binomial base ring. After
shewing how these functors are encoded by modules over a certain ring, we
record a precise criterion for a numerical (or polynomial) functor to admit a
strict polynomial structure in the sense of Friedlander & Suslin. We also
provide several characterisations of analytic functors
