Characterizing some regularities of ordered semigroups by their anti-hybrid ideals [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 We focus on mappings called hybrid structures. A hybrid structure can be regarded as a combination of a soft set and a fuzzy set. Therefore, with the help of the products of union softs sets and fuzzy sets, we can define a new product of hybrid ...

Elementary definability of the class of universal hypergraphic automata in the class of semigroups [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2022 Hypergraphic automata are automata, state sets and output symbol sets of which are hypergraphs, being invariant under actions of transition and output functions. Universally attracting objects in the category of hypergraphic automata are called universal

Fixed Point Theory and Applications, 2010 Motivated by the method of Xu (2006) and Matsushita and Takahashi (2008), we characterize the set of all common fixed points of a family of nonexpansive mappings by the notion of Mosco convergence and prove strong convergence theorems for nonexpansive ...

Fixed point theorems for a semigroup of total asymptotically nonexpansive mappings in uniformly convex Banach spaces [PDF]
Opuscula Mathematica, 2014 In this paper, we provide existence and convergence theorems of common fixed points for left (or right) reversible semitopological semigroups of total asymptotically nonexpansive mappings in uniformly convex Banach spaces.

On Uniformly Generalized Lipschitzian Mappings
Fixed Point Theory and Applications, 2010 We consider another class of generalized Lipschitzian type mappings and utilize the same to prove fixed point theorems for asymptotically regular and uniformly generalized Lipschitzian one-parameter semigroups of self-mappings defined on bounded metric ...

On a Class of Differential Variational Inequalities in Infinite-Dimensional Spaces
Mathematics, 2021 A new class of differential variational inequalities (DVIs), governed by a variational inequality and an evolution equation formulated in infinite-dimensional spaces, is investigated in this paper.

Fixed Point Theory and Applications, 2010 We prove strong convergence theorems for countable families of asymptotically nonexpansive mappings and semigroups in Hilbert spaces. Our results extend and improve the recent results of Nakajo and Takahashi (2003) and of Zegeye and Shahzad (2008) from ...

Metric domains, holomorphic mappings and nonlinear semigroups
Abstract and Applied Analysis, 1998 We study nonlinear semigroups of holomorphic mappings on certain domains in complex Banach spaces. We examine, in particular, their differentiability and their representations by exponential and other product formulas.

Maximal subsemigroups of the semigroup of all mappings on an infinite set [PDF]
, 2013 In this paper we classify the maximal subsemigroups of the \emph{full transformation semigroup} $\Omega^\Omega$, which consists of all mappings on the infinite set $\Omega$, containing certain subgroups of the symmetric group $\sym(\Omega)$ on $\Omega ...
