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…

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…

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…
