Abstract
The periodicity conjecture for pairs of Dynkin diagrams was formulated at the beginning of the nineties in mathematical physics, in work of Zamolodchikov, Ravanini-Tateo-Valleriani and Kuniba-Nakanishi. We outline a proof based on the machinery of Fomin-Zelevinsky's cluster algebras and their (additive) categorification via 2-Calabi-Yau categories.
