Cayley Graph Expanders and Groups of Finite Width
Norbert Peyerimhoff, Alina Vdovina
We present new infinite families of expander graphs of vertex degree 4, which is the minimal possible degree for Cayley graph expanders. Our first family defines a tower of coverin…

Geometric and spectral properties of locally tessellating planar graphs
Matthias Keller, Norbert Peyerimhoff
In this article, we derive bounds for values of the global geometry of locally tessellating planar graphs, namely, the Cheeger constant and exponential growth, in terms of combinat…
