Constructions of positive commutative semigroups on the plane, II
International Journal of Mathematics and Mathematical Sciences, 1985 A positive semiroup is a topological semigroup containing a subsemigroup N isomorphic to the multiplicative semigroup of nonnegative real numbers, embedded as a closed subset of E2 in such a way that 1 is an identity and 0 is a zero.

Characterizations of Regular Ordered Semirings by Ordered Quasi‐Ideals
International Journal of Mathematics and Mathematical Sciences, Volume 2016, Issue 1, 2016., 2016 We introduce the notion of an ordered quasi‐ideal of an ordered semiring and show that ordered quasi‐ideals and ordered bi‐ideals coincide in regular ordered semirings. Then we give characterizations of regular ordered semirings, regular ordered duo‐semirings, and left (right) regular ordered semirings by their ordered quasi‐ideals.

Special Functions of Hypercomplex Variable on the Lattice Based on SU(1,1)
Symmetry, Integrability and Geometry: Methods and Applications, 2013 Based on the representation of a set of canonical operators on the lattice hZn, which are Clifford-vector-valued, we will introduce new families of special functions of hypercomplex variable possessing su(1,1) symmetries. The Fourier decomposition of the

On the Dolbeault–Dirac operator of quantized symmetric spaces
Transactions of the London Mathematical Society, Volume 2, Issue 1, Page 33-56, 2015., 2015 The Dolbeault complex of a quantized compact Hermitian symmetric space is expressed in terms of the Koszul complex of a braided symmetric algebra of Berenstein and Zwicknagl. This defines a spectral triple quan‐tizing the Dolbeault–Dirac operator associated to the canonical spin c structure.

The sympathetic sceptic's guide to semigroup representations [PDF]
, 2021 This is an elementary, examples driven, introduction to the representation theory of finite semigroups. We illustrate the Clifford-Munn correspondence between the representations of a semigroup and the representations of its maximal subgroups.

On Endomorphism Universality of Sparse Graph Classes
Journal of Graph Theory, Volume 110, Issue 2, Page 223-244, October 2025.ABSTRACT We show that every commutative idempotent monoid (a.k.a. lattice) is the endomorphism monoid of a subcubic graph. This solves a problem of Babai and Pultr and the degree bound is best‐possible. On the other hand, we show that no class excluding a minor can have all commutative idempotent monoids among its endomorphism monoids. As a by‐product,

The Structure of φ‐Module Amenable Banach Algebras
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 We study the concept of φ‐module amenability of Banach algebras, which are Banach modules over another Banach algebra with compatible actions. Also, we compare the notions of φ‐amenability and φ‐module amenability of Banach algebras. As a consequence, we show that, if S is an inverse semigroup with finite set E of idempotents and l1(S) is a commutative

Green index in semigroups : generators, presentations and automatic structures
, 2012 The Green index of a subsemigroup T of a semigroup S is given by counting strong orbits in the complement S n T under the natural actions of T on S via right and left multiplication.
