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.

The independent resolving number of a graph [PDF]

open access: yesMathematica Bohemica, 2003
Summary: For an ordered set \(W = \{w_1, w_2, \dots , w_k\}\) of vertices in a connected graph \(G\) and a vertex \(v\) of \(G\), the code of \(v\) with respect to \(W\) is the \(k\)-vector \[ c_W (v) = (d (v, w_1), d (v, w_2), \dots , d (v, w_k)). \] The set \(W\) is an independent resolving set for \(G\) if (1) \(W\) is independent in \(G\) and (2 ...

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 $i=1,2,...,n-1$.

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.

On the Independence Number of Traceable 2-Connected Claw-Free Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
A well-known theorem by Chvátal-Erdőos [A note on Hamilton circuits, Discrete Math. 2 (1972) 111–135] states that if the independence number of a graph G is at most its connectivity plus one, then G is traceable.

Independence number in graphs and its upper bounds [PDF]

open access: yesJournal of Mahani Mathematical Research
‎In this paper, we use the double counting method to find some upper bounds for the independence number of a simple graph in terms of its order, size and  maximum degree.   Moreover,  we determine extremal graphs attaining equality in upper bounds.

Note on the smallest root of the independence polynomial [PDF]

open access: yes, 2013
One can define the independence polynomial of a graph G as follows. Let i(k)(G) denote the number of independent sets of size k of G, where i(0)(G) = 1. Then the independence polynomial of G is I(G,x) = Sigma(n)(k=0)(-1)(k)i(k)(G)x(k).

On the Number of Independent Functional Dependencies [PDF]

open access: yes, 2006
We will investigate the following question: what can be the maximum number of independent functional dependencies in a database of n attributes, that is the maximum cardinality of a system of dependencies which which do not follow from the Armstrong axioms and none of them can be derived from the remaining ones using the Armstrong axioms.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...
