Multi-Ordered Posets

open access: yes, 2007
Richard Stanley first introduced the idea of an r-differential poset in 1988. There are two well known types of differential posets: The first is the 1-differential poset of partitions called Young’s lattice and its generalization to the k-differential k-ribbon poset, and the second is the 1-differential Fibonacci lattice Z(1) and its generalization to

Fuzzy -Continuous Posets

open access: yesAbstract and Applied Analysis, 2013
The aim of this paper is to generalize fuzzy continuous posets. The concept of fuzzy subset system on fuzzy posets is introduced; some elementary definitions such as fuzzy -continuous posets and fuzzy -algebraic posets are given. Furthermore, we try to find some natural classes of fuzzy -continuous maps under which the images of such fuzzy algebraic ...

GENERALIZED ORTHOMODULAR POSETS

open access: yesDemonstratio Mathematica, 1991
The autor generalizes the notion of generalized orthomodular lattices, introduced by Janowitz, to the notion of generalized orthomodular posets GOMP. Every orthomodular poset is a GOMP. Every (weak) GOMP \(A\) can be embedded as an order ideal in an orthomodular poset \(P\) such that \(x\in A\) or \(x^ \bot\in A\) for every \(x\in P\).

Realization of Posets

open access: yesJournal of Graph Algorithms and Applications, 2002
We prove a very general representation theorem for posets and, as a corollary, deduce that any abstract simplicial complex S has a geometric realization in the Euclidean space of dimension P(S)-1, where P(S) is the Dushnik-Miller dimension of the face order of S.

Plane posets, special posets, and permutations

open access: yesAdvances in Mathematics, 2013
We study the self-dual Hopf algebra $\h\_{\SP}$ of special posets introduced by Malvenuto and Reutenauer and the Hopf algebra morphism from $\h\_{\SP}$ to to the Hopf algebra of free quasi-symmetric functions $\FQSym$ given by linear extensions. In particular, we construct two Hopf subalgebras both isomorphic to $\FQSym$; the first one is based on ...

Poset positional games

open access: yesDiscrete Mathematics
We propose a generalization of positional games, supplementing them with a restriction on the order in which the elements of the board are allowed to be claimed. We introduce poset positional games, which are positional games with an additional structure -- a poset on the elements of the board.
