EDGE IRREGULAR REFLEXIVE LABELING OF DUMBBELL GRAPH, CORONA OF OPEN LADDER, AND NULL GRAPH
BarekengGraph is a simple, connected, undirected graph with vertex set and edge set . A graph is called to have an edge irregular reflexive -labeling if its vertices can be labeled with even numbers from until and its edges can be labeled with ...

Null Model-Based Data Augmentation for Graph Classification [PDF]
IEEE Transactions on Network Science and Engineering, 2021 Graph classification is an important task widely applied to biochemistry, social networks, and other fields. Since it is a data-dependent problem, insufficient training data will deteriorate the performance of graph classification models. To address this

Edge irregular reflexive labeling on sun graph and corona of cycle and null graph with two vertices
Indonesian Journal of Combinatorics, 2021 Let G(V,E) be a simple and connected graph which set of vertices is V and set of edges is E. Irregular reflexive k-labeling f on G(V,E) is assignment that carries the numbers of integer to elements of graph, such that the positive integer {1,2, 3,...,ke}

Gallai-Edmonds decomposition of unicyclic graphs from null space [PDF]
The American Journal of Combinatorics, 2022 In this paper, we compute the Gallai-Edmonds decomposition of a unicyclic graph $G$ using linear algebraic tools. More precisely, the Gallai-Edmonds decomposition of $G$ is obtained from the null space associated with adjacency matrices of its subtrees.

On local antimagic chromatic numbers of circulant graphs join with null graphs or cycles
Proyecciones (Antofagasta), 2023 An edge labeling of a graph G = (V,E) is said to be local antimagic if there is a bijection f : E → {1,..., |E|} such that for any pair of adjacent vertices x and y, f +(x) ≠ f +(y), where the induced vertex label is f +(x) = 𝜮 f(e), with e ranging over ...

Edge Irregular Reflexive Labeling of Ladder Graph Corona Null Graph Families
European Journal of Pure and Applied MathematicsGiven a graph $G(V,E)$ or simply written as $G$. The graph labeling was first introduced in 1960, it is a function that mapping integers or labels to graph elements (vertices, edges, or both of them) which must satisfy some certain criteria.

The split-and-drift random graph, a null model for speciation [PDF]
Stochastic Processes and their Applications, 2017 We introduce a new random graph model motivated by biological questions relating to speciation. This random graph is defined as the stationary distribution of a Markov chain on the space of graphs on $\{1, \ldots, n\}$.

On Null Vertex in Bipolar Fuzzy Graphs
International Journal of Analysis and ApplicationsWe present a novel vertex in Bipolar fuzzy graph, null vertex, which is distinct from boundary vertex and interior vertex and also attempt a study on null vertex in bipolar fuzzy closed helm graph CHn.

Graph‐based spectrum sensing algorithm via nonlinear function regulation
IET Radar, Sonar & NavigationTo solve the difficulties in threshold selection and poor performance under low signal‐to‐noise ratio (SNR) conditions in existing spectrum sensing algorithms, a graph‐based spectrum sensing algorithm using nonlinear function regulation was proposed. The
