Odd Fibonacci edge irregular labeling for some trees obtained from subdivision and vertex identification operations

open access: yesمجلة بغداد للعلوم, 2023
Let G be a graph with p vertices and q edges and  be an injective function, where k is a positive integer. If the induced edge labeling   defined by for each is a bijection, then the labeling f is called an odd Fibonacci edge irregular labeling of G.

Subword complexes and edge subdivisions [PDF]

open access: yesProceedings of the Steklov Institute of Mathematics, 2014
For a finite Coxeter group, a subword complex is a simplicial complex associated with a pair (Q, π), where Q is a word in the alphabet of simple reflections, $π$ is a group element. We discuss the transformations of such a complex induced by braid moves of the word Q.

THE VERTEX DISTANCE COMPLEMENT SPECTRUM OF SUBDIVISION VERTEX JOIN AND SUBDIVISION EDGE JOIN OF TWO REGULAR GRAPHS

open access: yesUral Mathematical Journal, 2021
The vertex distance complement (VDC) matrix \(\textit{C}\), of a connected graph  \(G\) with vertex set consisting of \(n\) vertices, is a real symmetric matrix \([c_{ij}]\) that takes the value \(n - d_{ij}\) where \(d_{ij}\) is the distance between the

Variational reconstruction using subdivision surfaces with continuous sharpness control

open access: yesComputational Visual Media, 2017
We present a variational method for subdivision surface reconstruction from a noisy dense mesh. A new set of subdivision rules with continuous sharpness control is introduced into Loop subdivision for better modeling subdivision surface features such as ...

Narumi–Katayama index of the subdivision graphs

open access: yesJournal of Taibah University for Science, 2018
Subdivision is an important aspect in graph theory which allows one to calculate properties of some complicated graphs in terms of some easier graphs. Recently, the notion of r-subdivision was similarly defined as a quite useful generalization by adding ...

Multiplicative Zagreb indices and coindices of some derived graphs [PDF]

open access: yesOpuscula Mathematica, 2016
In this note, we obtain the expressions for multiplicative Zagreb indices and coindices of derived graphs such as a line graph, subdivision graph, vertex-semitotal graph, edge-semitotal graph, total graph and paraline graph.

Domination Subdivision and Domination Multisubdivision Numbers of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
The domination subdivision number sd(G) of a graph G is the minimum number of edges that must be subdivided (where an edge can be subdivided at most once) in order to increase the domination number of G. It has been shown [10] that sd(T) ≤ 3 for any tree

Irregularity Measures of Subdivision Vertex-Edge Join of Graphs

open access: yesJournal of Chemistry, 2021
The study of graphs and networks accomplished by topological measures plays an applicable task to obtain their hidden topologies. This procedure has been greatly used in cheminformatics, bioinformatics, and biomedicine, where estimations based on graph ...

Recursive Process for Constructing the Refinement Rules of New Combined Subdivision Schemes and Its Extended Form

open access: yesJournal of Mathematics, 2021
In this article, we present a new method to construct a family of 2N+2-point binary subdivision schemes with one tension parameter. The construction of the family of schemes is based on repeated local translation of points by certain displacement vectors.
