Power graphs provide an innovative way to visualise and analyse the algebraic structure of finite groups. In a power graph, the elements of a finite group serve as vertices, and an edge is drawn ...

This paper presents a non-technical exposition of graph theory (more particularly, the theory of directed graphs or digraphs), followed by a survey of the literature on applications of graph theory in ...

This paper summarizes the known results on graphs with smallest eigenvalue around -2, and completes the theory by proving a number of new results, giving comprehensive tables of the finitely many ...

The second type of graph store, property graphs, generally do not store RDF, and differ from semantic graphs in two critical ways. Nodes can store attributes (scalar values) and properties that ...

A mathematical abstraction of this type of setting is called a graph. The present course will study basic concepts, properties and applications of graphs. This will include a discussion of several ...

Graph theory, a nearly 300-year-old discipline considered an element of discrete mathematics, is used to model many types of relationships and processes in physical, biological, social and information ...

Solving sudoku puzzles may not require mathematics, but mathematicians have found plenty to say about the popular brainteasers.
