The study of such graphs is called graph theory. Engineers need to find planarity in a graph when, for example, they are designing a computer chip without a crossed wire.

Graph theory may show how individuals are connected, for example, but not capture the ways in which clusters of friends on social media influence each other’s behavior.

Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used ...

MARC NOY, VLADY RAVELOMANANA, JUANJO RUÉ, ON THE PROBABILITY OF PLANARITY OF A RANDOM GRAPH NEAR THE CRITICAL POINT, Proceedings of the American Mathematical Society, Vol. 143, No. 3 (MARCH 2015), pp.

A GRAPH is a very simple construction used to model things that can be described as objects and the connections between them. Graph theory is both an area of mathematics and an important tool in ...

Graph theory has a lot to say about how phenomena can grow, such as the spread of infectious diseases. There are different graphs, or networks, of relations, and they can affect things such as the ...
