# Trigroups and M-theory

## By John Huerta (CAMGSD, Instituto Superior Técnico, U. Lisboa)

A trigroup is a tricategory with one object and all 1-, 2- and 3-morphisms invertible [1]. M-theory is a mysterious branch of physics believed to unify the five 10D string theories and 11D supergravity. Without assuming any knowledge of physics, we will describe how the mathematics of M-theory leads naturally to a certain trigroup [2].
