Graph lambda theories

open access: yesMathematical Structures in Computer Science, 2008
A longstanding open problem in lambda calculus is whether there exist continuous models of the untyped lambda calculus whose theory is exactly the λβ or the least sensible λ-theory ℋ (which is generated by equating all the unsolvable terms). A related question is whether, given a class of lambda models, there are a minimal λ-theory and a minimal ...

Introduction to graph theory

open access: yesMathematical Gazette, 1973
In graph theory, the term graph refers to a set of vertices and a set of edges. A vertex can be used to represent any object. Graphs may contain undirected or directed edges. An undirected edge is a set of two vertices. A directed edge is an ordered pair

The Determinant of Matching Matrix in the Evaluation of Matching Polynomial

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2011
A characterization is given for graphs whose matching polynomial is the determinant of their matching matrices. The matching matrix is then modified and its relation with other graph polynomials is examined.

Graph Theory: A Lost Component For Development in Nigeria

open access: yesJournal of Nigerian Society of Physical Sciences, 2022
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.

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

open access: yesDiscussiones 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

Application of Graph Theory for Identifying Connectivity Patterns in Human Brain Networks: A Systematic Review

open access: yesFrontiers in Neuroscience, 2019
Background: Analysis of the human connectome using functional magnetic resonance imaging (fMRI) started in the mid-1990s and attracted increasing attention in attempts to discover the neural underpinnings of human cognition and neurological disorders. In

Solutions of Detour Distance Graph Equations

open access: yesSensors, 2022
Graph theory is a useful mathematical structure used to model pairwise relations between sensor nodes in wireless sensor networks. Graph equations are nothing but equations in which the unknown factors are graphs.
