Large flats in large subgraphs of fine curve graphs
Ryan Dickmann, Roberta Shapiro
The fine curve graph of a surface is a graph whose vertices are essential simple closed curves and whose edges connect disjoint curves. Following a rich history of hyperbolicity of…

A challenger to elliptic billiards fails: String construction over convex polygons and the Birkhoff--Poritsky conjecture
Leonid Bunimovich, Roberta Shapiro
We prove that the billiard claimed to be a possible counterexample to the Birkhoff-Poritsky conjecture is actually not a counterexample. We also show that for a billiard in a table…

Automorphisms of the k-curve graph
Shuchi Agrawal, Tarik Aougab, Yassin Chandran +4
Given a natural number k and an orientable surface S of finite type, define the k-curve graph to be the graph with vertices corresponding to isotopy classes of essential simple clo…
