Hi all,
My student Clovis Eberhart and I were led to consider certain
‘distributive’ squares of categories and functors, in the sense that
doing left then right Kan extension (of presheaves) along one side is
isomorphic to doing right then left along the other.
Does anyone please know if such squares have been studied somewhere?
Best wishes to all,
Tom
