Expansion properties of Whitehead moves on cubic graphs
Laura Grave de Peralta, Alexander Kolpakov
The present note concerns the "graph of graphs" that has cubic graphs as vertices connected by edges represented by the so-called Whitehead moves. Here, we prove that the outer-con…

High-dimensional expanders from Kac--Moody--Steinberg groups
Laura Grave de Peralta, Inga Valentiner-Branth
High-dimensional expanders are a generalization of the notion of expander graphs to simplicial complexes and give rise to a variety of applications in computer science and other fi…
