On Total H-Irregularity Strength of the Disjoint Union of Graphs
Discussiones Mathematicae Graph Theory, 2020 A simple graph G admits an H-covering if every edge in E(G) belongs to at least to one subgraph of G isomorphic to a given graph H. For the subgraph H ⊆ G under a total k-labeling we define the associated H-weight as the sum of labels of all vertices and

AKCE International Journal of Graphs and Combinatorics, 2020 I have known Lowell Beineke for almost fifty years. Our first joint paper, on edge-colorings of graphs, was initiated in 1971, and since then we have produced further articles and nine books on graph theory, with another two books currently in progress ...

Some Topological Concepts Via Graph Theory
Tikrit Journal of Pure Science, 2020 Due it is difficult to find applications in topological spaces, which are branches of pure mathematics, the importance of this paper is to find applications in graph theory.

The STEM Methodology and Graph Theory: Some Practical Examples
Mathematics, 2021 In this paper, we highlight that Graph Theory is certainly well suited to an applications approach. One of the basic problems that this theory solves is finding the shortest path between two points.

Detecting series periodicity with horizontal visibility graphs [PDF]
, 2010 The horizontal visibility algorithm has been recently introduced as a mapping between time series and networks. The challenge lies in characterizing the structure of time series (and the processes that generated those series) using the powerful tools of ...

Exact trace formulae for a class of one-dimensional ray-splitting systems [PDF]
, 2001 Based on quantum graph theory we establish that the ray-splitting trace formula proposed by Couchman {\it et al.} (Phys. Rev. A {\bf 46}, 6193 (1992)) is exact for a class of one-dimensional ray-splitting systems.
