Fixed point properties for semigroups of nonexpansive mappings on convex sets in dual Banach spaces
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018 It has been a long-standing problem posed by the first author in a conference in Marseille in 1990 to characterize semitopological semigroups which have common fixed point property when acting on a nonempty weak* compact convex subset of a dual Banach ...

Flows on Classes of Regular Semigroups and Cauchy Categories
Journal of Mathematics, 2019 We consider the structure of the flow monoid for some classes of regular semigroups (which are special case of flows on categories) and for Cauchy categories.

Algebras of right ample semigroups
Open Mathematics, 2018 Strict RA semigroups are common generalizations of ample semigroups and inverse semigroups. The aim of this paper is to study algebras of strict RA semigroups.

Proceedings of the American Mathematical Society, 1977 A Tarski semigroup is an algebraic system which mirrors a fragment of the additive theory of cardinal numbers. Here we show that any two such systems have the same universal theory. We also give a simple arithmetical necessary and sufficient condition for a universal sentence to hold in a Tarski semigroup.

On Interval-valued Anti Fuzzy Prime bi-ideal of Semigroup
Tikrit Journal of Pure Science, 2023 In this paper, we introduce the notions of interval-valued anti fuzzy prime (resp. strongly prime and semiprime) bi-ideals of semigroup. By using these ideas, we characterize those semigroup for which each interval anti-fuzzy bi-ideal is semiprime and ...

Journal of Algebra, 2000 In earlier articles of the first author it was shown how to construct an inverse semigroup from any tiling of Euclidean space. Such semigroups are called tiling semigroups. In the paper a categorical basis for such constructions is given in terms of an appropriate group acting partially and without fixed points on an inverse category associated with ...

Varieties of \u3cem\u3eP\u3c/em\u3e-Restriction Semigroups [PDF]
, 2014 The restriction semigroups, in both their one-sided and two-sided versions, have arisen in various fashions, meriting study for their own sake. From one historical perspective, as “weakly E-ample” semigroups, the definition revolves around a “designated ...

Holomorphicc-semigroups and holomorphic semigroups
Semigroup Forum, 1989 This paper is concerned with holomorphic C-semigroups. The main purpose is to give a characterization of the C-complete infinitesimal generator of a holomorphic C-semigroup, which coincides with that of a holomorphic \((C_ 0)\)-semigroup in the case of \(C=I\). We also clarify the relationship between holomorphic C-semigroups and holomorphic semigroups

Proceedings of the American Mathematical Society, 1983 Let S S be a semigroup of matrices over a field such that a power of each element lies in a subgroup (i.e., each element has a Drazin inverse within the semigroup). The main theorem of this paper is that there exist ideals I 0 , … ,

The Canadian Journal of Chemical Engineering, EarlyView.Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...
