Title
Limits of CohFTs with a non-flat unit, 3-spin and negative r-spin relations

Abstract
We show negative r-spin relations of Chidambaram, Giacchetto and Garcia-Failde are implied by the Pixton’s 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. Hence, we conclude that the negative r-spin relations hold in Chow. This is a joint work in-progress with Felix Janda.
