重言环中判别式附近的Frobenius流形与关系
Frobenius Manifolds near the Discriminant and Relations in the Tautological Ring
摘要：
我们给出了一个判别式的光滑点附近的广义半单（不一定是共形）Frobenius流形局部推广到上同调域论的准则。作为一个应用，我们表明，一个大的重言式关系的Givental-Teleman分类的任何一般半单上同调域论遵循Pixton的广义Faber-Zagier关系。
英文摘要：
We give a criterion for extending a generically semisimple (not necessarily conformal) Frobenius manifold locally near a smooth point of the discriminant to a cohomological field theory. As an application, we show that a large set of tautological relations related to the Givental--Teleman classification for any generically semisimple cohomological field theories follow from Pixton's generalized Faber--Zagier relations.
