On commutativity of a semigroup which is a semilattice of commutative semigroups
Journal of Algebra, 1969 Let P,(G) and P,(G) be abstract properties pertaining to commutative semigroups G in the sense of Cohn [3]. P,(G) is said to be weaker than or equal to P,(G) and denoted by P,(G) 3 P,(G) if and only if, for any commutative semigroup S, P,(G) is satisfied by S (i.e., P,(S) is true) whenever P,(G) is satisfied by S.

On the orbits of G-closure points of ultimately nonexpansive mappings
Fixed Point Theory and Applications, 2006 Let X be a closed subset of a Banach space and G an ultimately nonexpansive commutative semigroup of continuous selfmappings. If the G-closure of X is nonempty, then the closure of the orbit of any G-closure point is a commutative topological group.

On absorption in semigroups and $n$-ary semigroups [PDF]
Logical Methods in Computer Science, 2015 The notion of absorption was developed a few years ago by Barto and Kozik and immediately found many applications, particularly in topics related to the constraint satisfaction problem.

A Note on Locally Inverse Semigroup Algebras
International Journal of Mathematics and Mathematical Sciences, 2008 Let R be a commutative ring and S a finite locally inverse semigroup. It is proved that the semigroup algebra R[S] is isomorphic to the direct product of Munn algebras ℳ(R[GJ],mJ,nJ;PJ) with J∈S/𝒥, where mJ is the number of ℛ-classes in J, nJ the

On commutation semigroups of dihedral groups [PDF]
Semigroup Forum, 2013 For G a group and g in G, we define mappings pg(G) and lg(G) from G into G by pg(x)=[x,g] and lg(x)=[g,x]. We let P(G) and L(G) denote the subsemigroups of the set of all mappings from G to G generated by {pg: g in G} and {lg: g in G}, respectively. P(G) and L(G) are called the right and left commutation semigroup of G, respectively.
