Graphs and networks are powerful tools for representing connections or relationships between objects or people. They belong to a branch of mathematics called graph theory which is quite distinct from ...

If all the Seidel eigenvalues of the graph G are integers, then G is called a Seidel integer graph. In this paper, we apply methods from algebraic and matrix theory to obtain the Seidel eigenvalue ...

Figure 1. A simple example of a knowledge graph. In the biomedical domain, entities represented in a knowledge graph can be, for example, molecules, biological functions and diseases or phenotypes.

This is the power of graph theory. However, graph theory doesn’t stop at social networks. It finds applications in everything from brain signal processing to solving Sudoku and airline scheduling.
