Title: Could representations of your category be those of a groupoid?
Abstract:
By a representation of a category F here is meant a functor from F to a 
category V of
modules over a commutative ring R. The question is whether there is a 
groupoid G whose
category [G,V] of representations is equivalent to the category [F,V] of 
representations
of the given category F. That is to say, is there a groupoid G such that 
the free V -
category RG on G is Morita V - equivalent to the free V - category RF on 
F ? The groupoid
G could be the core groupoid Finv of F; that is, the subcategory of F 
with the same
objects but with only the invertible morphisms. Motivating examples come 
from Dold-Kan type theorems and a theorem of Nicholas Kuhn [see “Generic 
representation theory of finite
fields in nondescribing characteristic”, Advances in Math 272 (2015) 
598–610]. The plan is
to describe structure on F which leads to such a result, and includes 
these and other examples.
