Ranganathan–Wise conjecture. The differential $\eta$ is smoothable if and only if, for every level $i$:

Let $\mathcal{M}_g(2g-1)$ be the minimal stratum of differentials, let $\chi(\mathcal{M}_g(2g-1))^{\rm spin}$ denote its spin Euler characteristic, and let…

Let ${\mathcal{M}}_g(2g-1)$ denote the moduli space of minimal holomorphic strata of differentials in genus $g$, and let $\chi$ denote its orbifold Euler characteristic. Asymptotic…
