The pentagram map and Y-patterns

Max Glick (1)

Abstract
English
The pentagram map, introduced by R. Schwartz, is defined by the following construction: given a polygon as input, draw all of its ``shortest'' diagonals, and output the smaller polygon which they cut out. We employ the machinery of cluster algebras to obtain explicit formulas for the iterates of the pentagram map.
French
L'application pentagramme de R. Schwartz est définie par la construction suivante: on trace les diagonales ``les plus courtes'' d'un polygone donné en entrée et on retourne en sortie le plus petit polygone que ces diagonales découpent. Nous employons la machinerie des algèbres ``clusters'' pour obtenir des formules explicites pour les itérations de l'application pentagramme.
