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

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 ...
