Now that pandemic restrictions are easing up, people are getting together again. But it’s been a while, so if you and your friends need some help breaking the ice, here’s a mathematical party game you ...

Graph labeling and colouring constitute a vibrant area of combinatorial mathematics concerned with the systematic assignment of discrete labels or colours to graph elements—typically vertices, edges ...

Graph Signal Processing (GSP) extends classical signal processing to data defined on irregular domains represented by graphs. In GSP, measurements or features are treated as signals on the vertices of ...

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 ...
