Analytic Functors

Description:  Analytic functors of Andre Joyal, who considered them in the categories of sets or vector spaces, are generalized to all symmetric monoidal categories. Whereas for Set these are precisely the finitary functors weakly preserving wide pullbacks, in other categories this characterization does not hold. A characterization of enriched endofunctors of vector spaces weakly preserving wide pullbacks is presented.
