Boolean Dimension and Local Dimension [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2017
Dimension is a standard and well-studied measure of complexity of posets. Recent research has provided many new upper bounds on the dimension for various structurally restricted classes of posets. Bounded dimension gives a succinct representation of the poset, admitting constant response time for queries of the form "is ...

The Effect of Resin Matrix on the Properties of CF/PEI and CF/PAEK Thermoplastic Composites

open access: yesInternational Journal of Polymer Science, 2023
As the adhesive for composites, the resin matrix directly impacts the molding process and product performance of thermoplastic composites (TPCs). Carbon fiber-reinforced polyetherimide (CF/PEI) and polyaryletherketone (CF/PAEK) composites were prepared ...

Sparsity and Dimension [PDF]

open access: yesCombinatorica, 2015
We prove that posets of bounded height whose cover graphs belong to a fixed class with bounded expansion have bounded dimension. Bounded expansion, introduced by Nešetřil and Ossona de Mendez as a model for sparsity in graphs, is a property that is naturally satisfied by a wide range of graph classes, from graph structure theory (graphs excluding a ...

The neutrosophic vector spaces - another approach [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
In this paper, we introduce and define a new version of a neutrosophic vector space. Indeed, this approach is a generalization of the notion of fuzzy vector space. Also, we study the neutrosophic subspace and linear independence.

Comparing Dushnik-Miller Dimension, Boolean Dimension and Local Dimension [PDF]

open access: yesOrder, 2019
The original notion of dimension for posets is due to Dushnik and Miller and has been studied extensively in the literature. Quite recently, there has been considerable interest in two variations of dimension known as Boolean dimension and local dimension.
