我们介绍并研究了寻找 M ́0,n$$ {overline{mathrm{M}}}_{0,n} $$ 上的共形分块除数非零的充要条件问题,完全解决了 sl2$$ mathfrak{s}{mathfrak{l}}_2 $$ 的问题。我们在 A 型中给出了必要的非零条件,当 theta 和临界水平重合时,这些条件就足够了。我们还表明除数受加性恒等式的影响,反映了权重和水平的分解。
We introduce and study the problem of finding necessary and sufficient conditions under which a conformal blocks divisor on M¯0,n$$ {overline{mathrm{M}}}_{0,n} $$ is nonzero, solving the problem completely for sl2$$ mathfrak{s}{mathfrak{l}}_2 $$. We give necessary nonvanishing conditions in type A, which are sufficient when theta and critical levels coincide. We also show divisors are subject to additive identities, reflecting a decomposition of the weights and level.
