Abstract

Skew pentagram maps act on polygons by intersecting diagonals of different lengths. They were introduced by Khesin-Soloviev in 2015 as conjecturally non-integrable generalizations of the pentagram map. In this talk, we show that certain skew pentagram maps have exponential degree growth and no preserved fibration.
