Simple vs non-simple loops on random regular graphs

Benjamin Dozier, Jenya Sapir

In this note we solve the ``birthday problem'' for loops on random regular graphs. Namely, for fixed $d \geq 3$ , we prove that on a random $d$ -regular graph with $n$ vertices, as $n$ …

Enumerative properties of triangulations of spherical bundles over S^1

Jacob Chestnut, Jenya Sapir, Ed Swartz

We give a complete characterization of all possible pairs (v,e), where v is the number of vertices and e is the number of edges, of any simplicial triangulation of an S^k-bundle ov…
