Semigroups and Their Subsemigroup Lattices WHO International Programme on Chemical Safety Danach werde ich die Unterschiede0. 1. General remarks. For any algebraic system A, the set SubA of all subsystems of A partially ordered by inclusion forms a lattice. This is the subsystem lattice of A. (In certain cases, such as that of semigroups, in order to have the right always to say that SubA is a lattice, we have to treat the empty set as a subsystem.) The study of various inter relationships between systems and their subsystem lattices is a rather large field of
