class sage.categories.partially_ordered_monoids.PartiallyOrderedMonoids[source]

Bases: Category_singleton

The category of partially ordered monoids, that is partially ordered sets which are also monoids, and such that multiplication preserves the ordering: \(x \leq y\) implies \(x*z < y*z\) and \(z*x < z*y\).
