Markov numbers are integers that appear in triples which are solutions of a Diophantine equation, the so-called Markov cubic x2 + y2 + z2 = 3 xyz.
A classical topic in number theory, these numbers are related to many areas of mathematics such as combinatorics, hyperbolic geometry, approximation theory and cluster algebras.
- explain the geometry of the norm and how it can be used to prove new identities for lengths of simple closed geodesics
