In this talk, we review the construction of N-Mixed-Spin-P fields by Chang-Guo-Li-Li and its localization and decomposition properties. Then we sketch a key step of the proof of Yamaguchi-Yau's polynomial structure. In this step, we define the R-matrix via the factorization between local and global S-matrices and relate the local and global CohFT using the R-matrix action.
