On θ-commutators and the corresponding non-commuting graphs

open access: yesOpen Mathematics, 2017
The θ-commutators of elements of a group with respect to an automorphism are introduced and their properties are investigated. Also, corresponding to θ-commutators, we define the θ-non-commuting graphs of groups and study their correlations with other ...

ON THE GIRTH, INDEPENDENCE NUMBER, AND WIENER INDEX OF COPRIME GRAPH OF DIHEDRAL GROUP

open access: yesBarekeng, 2023
The coprime graph of a finite group , denoted by , is a graph with vertex set  such that two distinct vertices  and  are adjacent if and only if their orders are coprime, i.e.,  where |x| is the order of x.

When can statistical theories be causally closed? [PDF]

open access: yes, 2004
The notion of common cause closedness of a classical, Kolmogorovian probability space with respect to a causal independence relation between the random events is defined, and propositions are presented that characterize common cause closedness for ...

Tree decompositions with bounded independence number: beyond independent sets

open access: yes, 2022
We continue the study of graph classes in which the treewidth can only be large due to the presence of a large clique, and, more specifically, of graph classes with bounded tree-independence number. In [Dallard, Milanič, and Štorgel, Treewidth versus clique number. {II}.

The possibilities of an independent special rapporteur scheme [PDF]

open access: yes, 2011
The independence and impartiality of the special rapporteurs is undoubtedly one of considerable importance to their work. In the context of the special procedures operating under the auspices of the Human Rights Council, a number of questions arise: what

Bounds for the Independence Number in $k$-Step Hamiltonian Graphs [PDF]

open access: yesComputer Science Journal of Moldova, 2018
For a given integer $k$, a graph $G$ of order $n$ is called $k$-step Hamiltonian if there is a labeling $v_1,v_2,...,v_n$ of vertices of $G$ such that $d(v_1,v_n)=d(v_i,v_{i+1})=k$ for $i=1,2,...,n-1$.

Abstract Interactions and Interaction Refinement in Model-Driven Design [PDF]

open access: yes, 2005
In a model-driven design process the interaction between application parts can be described at various levels of platform-independence. At the lowest level of platform-independence, interaction is realized by interaction mechanisms provided by specific ...

Two sufficient conditions for fractional k-deleted graphs

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
Let G be a graph, and k a positive integer. A fractional k-factor is a way of assigning weights to the edges of a graph G (with all weights between 0 and 1) such that for each vertex the sum of the weights of the edges incident with that vertex is k.
