Fix $r>0$. For integers $k$, $n$, and labels $a_1,\ldots,a_n$, consider the difference of conformal-block divisors on $\overline{\mathcal{M}}_{0,n}$ associated with the Virasoro ve…

Let $V=\text{Vir}_{2,2k+1}$, and let $\{W_{a_i}\}_{i=1}^n$ be a set of nontrivial simple $V$-modules, with $a_i\neq 1$. Let…
