Prime Labeling of H- Super Subdivision of Y-tree Related Graphs

open access: yesRatio Mathematica, 2023
A graph G with p points is called a prime labeling , if it possible to label the points x 2 V with distinct labels f(x) from f1;2; :::; pg in such a way that for each line e = uv gcd (f(u); f(v)) = 1 .

Application of the Combinatorial Nullstellensatz to Integer-magic Graph Labelings

open access: yesTheory and Applications of Graphs, 2022
Let $A$ be a nontrivial abelian group and $A^* = A \setminus \{0\}$. A graph is $A$-magic if there exists an edge labeling $f$ using elements of $A^*$ which induces a constant vertex labeling of the graph.

Even-Odd Prime Harmonious Graphs [PDF]

open access: yesPandian Journal of Mathematical Sciences, 2022
The paper considers finite and undirected simple connected graphs. Usually, graph labeling is an assignment of integers to the vertices or edges in the method.

On prime labellings

open access: yesDiscrete Mathematics, 1994
The paper is devoted to the study of prime graphs, that is finite graphs that admit a prime labelling. A prime labelling of a graph \(G=(V,E)\) is a bijection \(f: V\to \{1,2,\dots,| V|\}\) such that if \(e= \{u,v\}\in E\) then \(\text{GCD}(f(u),f(v))= 1\). Some results concerning bipartite graphs are obtained; all trees of order up to 15 are proved to

Imaging trans-cellular neurexin-neuroligin interactions by enzymatic probe ligation. [PDF]

open access: yesPLoS ONE, 2013
Neurexin and neuroligin are transmembrane adhesion proteins that play an important role in organizing the neuronal synaptic cleft. Our lab previously reported a method for imaging the trans-synaptic binding of neurexin and neuroligin called BLINC (Biotin

sc-graphs

open access: yesRatio Mathematica, 2023
Any graph operation of a graph drive only one graph structure. But eccentric graph operation of almost all the graphs drives more than one graph structure, which are interesting and marvelous one. The eccentric graph of G is denoted by ecc(G).

Prime Labelings of Snake Graphs

open access: yesThe PUMP Journal of Undergraduate Research, 2019
A prime labeling of a graph G with n vertices is a labeling of the vertices with distinct integers from the set {1, 2 ,..., n} such that the labels of any two adjacent vertices are relatively prime. In this paper, we introduce a snake graph, the fused union of identical cycles, and define a consecutive snake prime labeling for this new family of graphs.

Frequency Assignment Model of Zero Divisor Graph

open access: yesJournal of Applied Mathematics, 2021
Given a frequency assignment network model is a zero divisor graph Γ=V,E of commutative ring Rη, in this model, each node is considered to be a channel and their labelings are said to be the frequencies, which are assigned by the L2,1 and L3,2,1 labeling

Conflict vs Causality in Event Structures [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
Event structures are one of the best known models for concurrency. Many variants of the basic model and many possible notions of equivalence for them have been devised in the literature.
