MSP theory for smooth Calabi-Yau threefolds in weighted ${\mathbb{P}}^4$

Abstract

We develop the theory of $N$-mixed-spin-$P$ fields for Fermat-type hypersurfaces in $\mathbb{P}(1,1,1,1,2)$, $\mathbb{P}(1,1,1,1,4)$, and $\mathbb{P}(1,1,1,1,4)$, following the theory developed in arXiv:1809.08806 for the quintic threefold.
