Title:Markov equation and the most irrational numbers
Seminar:MASS Colloquium
Speaker:Alexander Veselov, Loughborough University, UK
Abstract:
You probably know that the golden ratio is "the most irrational number", although a precise meaning of this is not so obvious. You might be able to guess "the second most irrational number", but you certainly will be very surprised to see the bronze medallist. It turns out that the hierarchy of the most irrational numbers is governed by a remarkable Diophantine equation called Markov equation. I will tell you about this story going back to XIX century with a surprising modern twist linking it with enumerative geometry and theory of Painleve equations.
