Critical loci of self-maps of projective space

Matt Olechnowicz, Max Weinreich

Let $K$ be an algebraically closed field and let $n, d \geq 2$ . We show that the critical scheme of a general endomorphism of $P_{K}^{n}$ of degree $d$ is an integral hypersur…

Degree growth of skew pentagram maps

Max Weinreich

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…

Configurations of 10 points and their incidence varieties

Kelly Isham, Nathan Kaplan, Sam Kimport +3

Incidence varieties are spaces of $n$ -tuples of points in the projective plane that satisfy a given set of collinearity conditions. We classify the components of incidence varietie…

Algebraic billiards in the Fermat hyperbola

Max Weinreich

We prove two results on the algebraic dynamics of billiards in generic algebraic curves of degree $d \geq 2$ . First, the dynamical degree grows quadratically in $d$ ; second, the se…
