On semigroup presentations that define a group
, 2014 We consider the finite semigroup presentations of the form P=?a1,...an|w1=a1,..,wn=an?>and their Adian graphs. It is known that if both Adian graphs of P are connected and if one of the Adian graphs of P is a cycle graph then P defines a group (see 2008).

A presentation for the singular part of the full transformation semigroup
, 2010 The (full) transformation semigroup Tn is the semigroup of all functions from the finite set {1, . . . , n} to itself, under the operation of composition. The symmetric group Sn ⊆ Tn is the group of all permutations on {1, . . .

On representation of semigroups of inclusion hyperspaces
Karpatsʹkì Matematičnì Publìkacìï, 2010 Given a group $X$ we study the algebraic structure of the compactright-topological semigroup $G(X)$ consisting of inclusionhyperspaces on $X$. This semigroup contains the semigroup$lambda(X)$ of maximal linked systems as a closed subsemigroup.We ...

Semigroups of order-decreasing transformations
, 2012 Let X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this Thesis the study of order-increasing full (partial, partial one-to-one) transformations has been

Partial maps with domain and range: extending Schein's representation
, 2009 The semigroup of all partial maps on a set under the operation of composition admits a number of operations relating to the domain and range of a partial map. Of particular interest are the operations R and L returning the identity on the domain of a map

Smarandache Soft Semigroups and their Properties
Journal of New Theory, 2015 – In this paper, the notions of smarandache soft semigroups (SS-semigroups) introduced for the first time. An SS-semigroup ( , ) is basically a parameterized collection of subsemigroups which has F A is basically a parameterized collection of ...

Generalized Polynomials on Semigroups
Annales Mathematicae SilesianaeThis article has two main parts. In the first part we show that some of the basic theory of generalized polynomials on commutative semi-groups can be extended to all semigroups.
