Sandwich semigroups in locally small categories I: foundations
© 2018, Springer Nature Switzerland AG. Fix (not necessarily distinct) objects i and j of a locally small category S, and write Sijfor the set of all morphisms i→ j. Fix a morphism a∈ Sji, and define an operation ⋆aon Sijby x⋆ay= xay for all x, y∈ Sij. Then (Sij, ⋆a) is a semigroup, known as a sandw...
