Circular Flows in Planar Graphs

Daniel W. Cranston, Jiaao Li

For integers $a \geq 2 b > 0$ , a \emph{circular $a / b$ -flow} is a flow that takes values from ${\pm b, \pm (b + 1), \dots, \pm (a - b)}$ . The Planar Circular Flow Conjecture states that ever…

A Note on Bootstrap Percolation Thresholds in Plane Tilings using Regular Polygons

Neal Bushaw, Daniel W. Cranston

In \emph{ $k$ -bootstrap percolation}, we fix $p \in (0, 1)$ , an integer $k$ , and a plane graph $G$ . Initially, we infect each face of $G$ independently with probability $p$ . Infected…
