Four mathematicians have found a new upper limit to the “Ramsey number,” a crucial property describing unavoidable structure in graphs.

For decades, mathematicians have been inching forward on a problem about which sets contain evenly spaced patterns of three numbers. Last month, two computer scientists blew past all of those results.

In a recent paper, two mathematicians showed that a particular pattern is unavoidable when fractions are categorized.

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside.

A new proof shows that a knot some thought would contradict the famed slice-ribbon conjecture doesn’t.

Mathematicians are taking ideas developed to study random numbers and applying them to a broad range of categories.

Mathematicians are finding inevitable structures in sufficiently large sets of integers.

Lattice cryptography promises to protect secrets from the attacks of far-future quantum computers.

Recent explorations of unique geometric worlds reveal perplexing patterns, including the Fibonacci sequence and the golden ratio.
