Continuity in Partially Ordered Sets [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
The notion of a continuous domain is generalized to include posets which are not dcpos and in which the set of elements way below an element is not necessarily directed. We show that several of the pleasing algebraic and topological properties of domains

A Notion of Convergence in Fuzzy Partially Ordered Sets

open access: yesMathematics, 2020
The notion of sequential convergence in fuzzy partially ordered sets, under the name oF-convergence, is well known. Our aim in this paper is to introduce and study a notion of net convergence, with respect to the fuzzy order relation, named o-convergence,

Graphical partially ordered sets

open access: yesDiscrete Applied Mathematics, 1987
The main results of this paper can be found in a generalization of reconstruction properties to a large class of combinatorial structures by a concept of g-graph. For example in the section 3, the author shows many results about the reconstruction conjecture: many of them are known for graphs, but author's proof generalizes them for digraphs ...

Ramsey Numbers for Partially-Ordered Sets [PDF]

open access: yesOrder, 2018
We present a refinement of Ramsey numbers by considering graphs with a partial ordering on their vertices. This is a natural extension of the ordered Ramsey numbers. We formalize situations in which we can use arbitrary families of partially-ordered sets to form host graphs for Ramsey problems. We explore connections to well studied Turán-type problems

Shaprly transitive partially ordered sets

open access: yesDiscrete Mathematics, 1986
If \(\Lambda\) is a p.o. set, \(A=Aut(\Lambda,\leq)\) will denote its group of automorphisms. If for each \(\lambda_ 1,\lambda_ 2\in \Lambda\) there is a unique \(a\in A\) such that \(\lambda_ 1a=\lambda_ 2\), we say that \(\Lambda\) is sharply transitive. It is easily seen that any sharply transitive p.o. set is connected or has just 2 elements.

The Fuzzy Prime Spectrum of Partially Ordered Sets

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2023
We study the space of prime fuzzy ideals (and the space of maximal fuzzy ideals as a subspace) equipped with the hull-kernel topology in partially ordered sets.

An Efficient Algorithm for Decomposition of Partially Ordered Sets

open access: yesJournal of Mathematics, 2023
Efficient time complexities for partial ordered sets or posets are well-researched field. Hopcroft and Karp introduced an algorithm that solves the minimal chain decomposition in O (n2.5) time. Felsner et al.

An Integer Linear Programming Model for Partially Ordered Sets

open access: yesJournal of Mathematics, 2022
Linear programming is an important approach that is used to represent a large class of combinatorial optimization problems. The simplex algorithm is one of the algorithms for solving linear programming problems with exponential time complexity ...

On the cardinality of layers in some partially ordered sets

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
In this paper, we explicitly calculated additional terms of cardinality asymptotics of layers in the n-dimensional k-valued lattice Enk for odd k as n → ∞. The main term had been previously determined by V.B.

Orthomodular Lattices Induced by the Concurrency Relation [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2009
We apply to locally finite partially ordered sets a construction which associates a complete lattice to a given poset; the elements of the lattice are the closed subsets of a closure operator, defined starting from the concurrency relation. We show that,
