Chip-firing groups of iterated cones

Morgan V. Brown, Jackson S. Morrow, David Zureick-Brown

Let $\Gamma$ be a finite graph and let ${\Gamma }_n$ be the "$n$th cone over $\Gamma$" (i.e., the join of $\Gamma$ and the complete graph $K_n$). We study the asymptotic structure of the chip-firing grou…
