In this paper, we consider some category-theoretic properties of the category Pos-S of all S-
posets (posets equipped with a compatible right action of a pomonoid S), with monotone …

An increasing amount of twenty-first century metaphysics is couched in explicitly
hyperintensional terms: concepts such as grounding, fundamentally and metaphysical …

In this paper we study the notion of injectivity in the category Pos-S of S-posets for a
pomonoid S. First we see that, although there is no non-trivial injective S-poset with respect …

In this paper, we use two approaches to define the concept of fuzzy nominal sets: classic
and universal algebraic. We see that the fuzzy nominal sets obtained using the universal …

No need to say that the study of injectivity with respect to different classes of
monomorphisms is crucial in any category. In this paper, the notion of injectivity with respect …

Closure operators have been used in Algebra and Topology. Wellknown examples are the
closure of a subspace of a topological space, or the normal closure of a subgroup of a …

In this paper some properties of weak regular injectivity for S-posets, where S is a pomonoid,
are studied. The behaviour of different kinds of weak regular injectivity with products …

It is known that although the Baer Criterion for injectivity holds for modules over rings with
unit, it is not true for acts over an arbitrary monoid. Seeking a characterization for the Baer …

In this paper, some categorical properties of the category Cpo-S of all S-cpo's; cpo's
