Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and lines) to represent data. If you’ve ever drooled over a cherry pie, cut into ...

Thursday marks Pi Day, otherwise known as 3.14, which is the ratio of a circle's circumference to its diameter. While the average person can easily remember the rounded 3.14 ratio, the exact ratio has ...

Alan Veliz-Cuba has received funding from the Simons Foundation and the American Mathematical Society for some of his research. You can probably think of a time when you’ve used math to solve an ...

Sure, you can cut a pie into pieces, but what if it’s in four dimensions? Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and ...
