Some people have conjectured that this monstrous graph snares nearly every present-day mathematician and has threads into the physical, life, and social sciences (and even into movies and baseball).

Add the next, and the sum will be odd. Add the next, and the sum will be even, and so on. If you add an odd number of odd numbers, the sum has to be odd. But because the degree sum of any graph must ...

A graph in this case is any number of points, called nodes, connected by pairwise relations, called edges. In other words, an edge is a curve that connects two nodes.

Graph Crossing Number: The minimal number of edge crossings in any drawing of a graph in the plane. Join Product: An operation on two graphs that connects every vertex of one graph with every ...

Graph homomorphisms and chromatic numbers are foundational concepts in modern graph theory, with widespread applications that extend from combinatorial optimisation to theoretical computer science.
