DESCRIPTION:Frieze patterns are infinite strips of numbers satisfying cert
ain determinantal identities. Originally motivated by Gauss’ “miraculo
us pentagram” identities\, these patterns have since been connected to t
riangulations\, integrable systems\, representation theory\, and cluster a
lgebras. In this talk\, we will review a few characterizations and constru
ctions of frieze patterns\, as well as a generalization which allows friez
es with a “ragged edge” described by a juggling function. These “jug
gler’s friezes” correspond to special points in positroid varieties\,
in direct analogy with how classical friezes correspond to special points
in Grassmannians.\n\nhttps://indico.math.cnrs.fr/event/8421/
