WebLet us recall that a magma is a set S endowed with a binary operation S × S → S, 〈 x, y 〉 ↦ x y. If the binary operation is associative, then the magma S is called a semigroup. A semilattice is a commutative semigroup whose elements are idempotents. Each semilattice S carries a natural partial order ≤ defined by x ≤ y iff x y = y x ...
