This research topic explores the theoretical foundations and practical applications of graph labeling and coloring problems, both of which are central to modern combinatorics and computer science.

A theorem for coloring a large class of “perfect” mathematical networks could ease the way for a long-sought general coloring proof. Four years ago, the mathematician Maria Chudnovsky faced an all-too ...

In 1950 Edward Nelson, then a student at the University of Chicago, asked the kind of deceptively simple question that can give mathematicians fits for decades. Imagine, he said, a graph — a ...

This morning many hardcore Facebook users will be surprised when they login and look towards the iconic top blue bar. The coloring of Graph Search has been inverted and now features a bright white ...

Color can make it easier for people to identify important information, such as legends on an Excel graph. Professional designers learn to use color coding effectively to make websites, applications ...
