Apr 21, 2019 at 12:02 | comment | added | Simon Henry | @NajibIdrissi : well, here is an example: The free algebra on a module is a very simple, classical and well understood notion, and everybody know that Algebra are monadic over modules. On the other hand (unless you restrict to the conilpotent case) the 'cofree coalgebra' over a module is an awfully complicated object (in general: over a field, it is not as bad, but over $\mathbb{Z}$ it is truly awfull), to the point that people working in the fields don't always know if they exist or not. | |
Apr 21, 2019 at 7:53 | comment | added | YCor | @NajibIdrissi It might mean less popular as an explicitly used concept and language. | |
Apr 21, 2019 at 6:41 | comment | added | Najib Idrissi | I don't see how comonads are less popular. Coalgebras are a rather common thing. Any time you write a diagonal $(x,x)$, you are implicitly using a coalgebra structure. | |
