in this paper, the notion of injectivity with respect to order dense embeddings in the category of $s$-posets, posets with a monotone action of a pomonoid $s$ on them, is studied. we give a criterion, like the baer condition for injectivity of modules, or skornjakov criterion for injectivity of $s$-sets, for the order dense injectivity. also, we consider such injectivit...

In this paper we take $mathcal A$ to be the category {bf Pos-S} of $S$-posets, for a posemigroup $S$, ${mathcal M}_{pd}$ to be the class of partially ordered sequantially-dense monomorphisms and study the categorical properties, such as limits and colimits, of this class. These properties are usually needed to study the homological notions, such as injectivity, of $S$-...
Intuitively, a set is considered to be discrete if it is composed of isolated elements, whereas it is considered to be continuous if it is composed of infinite and contiguous elements and does not contain “holes”. More formally, to introduce the concept of continuous optimization, some preliminary definitions are required. If we consider sub-sets of real numbers, where the partial order is obvi...
the aim of conducting this study was to investigate the foreign language learning needs of undergraduate economics students and business management students in faculties of social sciences of alzahra and azad naragh university. in the study, which was designed on the basis of a qualitative-quantitative basis using interviews and questionnaires, 146 female undergraduate business management as we...
To investigate pathways to adjust the charge carrier concentration and optimize thermoelectric properties, we characterized structural thermal stability, performance of pristine Cl-doped Cu5+εSn2−εS7. We demonstrate that Cl doping in Cu5Sn2S7-type monoclinic compounds induces a collapse long-range cationic ordering, ultimately leading sphalerite-type cubic phase by ordered [Sn(S,Cl)4]x clusters...
We prove that every semigroup S in which the idempotents form a sub-semigroup has an E-unitary cover with the same property. Furthermore, if S is E-dense or orthodox, then its cover can be chosen with the same property. Then we describe the structure of E-unitary dense semigroups. Our results generalize Fountain's results on semigroups in which the idempotents commute, and are analogous to thos...
