From $3$-spin to Negative $r$-spin: Limits of Cohomological Field Theories and Tautological Relations

Deniz Genlik, Felix Janda

We prove that the negative $r$-spin tautological relations of Chidambaram--Garcia-Failde--Giacchetto are a consequence of Pixton's $3$-spin relations, for every $r\ge 2$, and deduce…
