Title: From 3-spin relations to negative r-spin relations
Abstract: We show negative r-spin relations of Chidambaram--Garcia-Failde--Giacchetto are implied by the Pixton’s 3-spin relations. To achieve this, mainly we extend a result of Janda to generically semi-simple CohFTs with a non-flat unit and perform a detailed asymptotic analysis of shifted Chiodo CohFT under the limit of a parameter. Consequently, we prove that the negative r-spin relations hold in the tautological Chow ring. This is a joint work with Felix Janda.
