Enumerating submonoids of finite commutative monoids

Caoilainn Kirkpatrick, Amelie el Mahmoud, Kyle Ormsby +6

Given a finite commutative monoid $M$ , we show that submonoids of $M \times [n]$ - where $[n] = {0, 1, \dots, n}$ is equipped with the max operation $\lor$ - may be enumerated via t…

Combinatorics of factorization systems on lattices

Jishnu Bose, Tien Chih, Hannah Housden +4

We initiate the combinatorial study of factorization systems on finite lattices, paying special attention to the role that reflective and coreflective factorization systems play in…
