Integral and unimodularity conjecture. The element $(\beta\!\rightharpoonup\!\lambda\bowtie r)$ should be a left integral of $D(H)$, at least when $H$ is unimodular; moreover,…

Conjecture. Integrals in $B^*$ can be extended to integrals in $\mathrm{H}(B)^*$.

Let $b6_s$ denote the stationary density of the infinite-volume abelian sandpile on $b6^2$. A formula for $b6_s$ reduces its evaluation to an integral that has been numerically eva…
