The sandpile group of polygon rings and twisted polygon rings

Haiyan Chen, Bojan Mohar

Let $C_{k_{1}}, \dots, C_{k_{n}}$ be cycles with $k_{i} \geq 2$ vertices ( $1 \leq i \leq n$ ). By attaching these $n$ cycles together in a linear order, we obtain a graph called a polygon cha…

The sandpile group of a polygon flower

Haiyan Chen, Bojan Mohar

Let $C_{t}$ be a cycle of length $t$ , and let $P_{1}, \dots, P_{t}$ be $t$ polygon chains. A polygon flower $F = (C_{t}; P_{1}, \dots, P_{t})$ is a graph obtained by identifying the $i$ th edge of…
