Classical and Quantum Cosmology of Multigravity [PDF]
Recently, a multigraviton theory on a simple closed circuit graph corresponding to the discretization of $S^1$ compactification of the Kaluza-Klein (KK) theory has been considered.

Pattern vectors from algebraic graph theory [PDF]
Graphstructures have proven computationally cumbersome for pattern analysis. The reason for this is that, before graphs can be converted to pattern vectors, correspondences must be established between the nodes of structures which are potentially of ...

On Total H-Irregularity Strength of the Disjoint Union of Graphs
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

Exploring the Power of Graph Theory in Hadron Theory: From Bound States to Quark Systems
The article discusses how graph theory has been utilized in hadron theory for high energy interactions in recent years. The paper emphasizes the significance of a visual perspective throughout the discussion and explores how graph theory can aid in ...

If \(k\) is a field and \(G\) is a graph on a vertex set \(\{v_ 1, \dots, v_ n\}\), then the edge ideal \(I = I(G) \subset R = k[x_ 1, \dots, x_ n]\) is generated by all \(x_ ix_ j\) such that \(v_ iv_ j\) is an edge of \(G\). We shall assume there are no edges of type \(v_ iv_ i\), so \(I\) is square-free and \(R/I\) is a special case of a face ring ...

The approach to criticality in sandpiles [PDF]
A popular theory of self-organized criticality relates the critical behavior of driven dissipative systems to that of systems with conservation. In particular, this theory predicts that the stationary density of the abelian sandpile model should be equal

Graph Theory: A Lost Component For Development in Nigeria
Graph theory is one of the neglected branches of mathematics in Nigeria but with the most applications in other fields of research. This article shows the paucity, importance, and necessity of graph theory in the development of Nigeria.

Sampling and Reconstruction of Sparse Signals on Circulant Graphs - An Introduction to Graph-FRI
With the objective of employing graphs toward a more generalized theory of signal processing, we present a novel sampling framework for (wavelet-)sparse signals defined on circulant graphs which extends basic properties of Finite Rate of Innovation (FRI)

On the Beta-Number of Forests with Isomorphic Components
The beta-number, β (G), of a graph G is defined to be either the smallest positive integer n for which there exists an injective function f : V (G) → {0, 1, . . .
