Letandbe two lists ofvariables, and consider the diagonal action ofon the exterior algebragenerated by these variables. Jongwon Kim and the 2nd author defined and studied thefermionic diagonal coinvariant ringobtained fromby modding out by the ideal generated by the-invariants with vanishing constant term. On the other hand, the 2nd author described an action ofon the vector space with basis given by noncrossing set partitions ofusing a novel family of skein relations that resolve crossings in set partitions. We give an isomorphism between a natural Catalan-dimensional submodule ofand the skein representation. To do this, we show that set partition skein relations arise naturally in the context of exterior algebras. Our approach yields an-equivariant way to resolve crossings in set partitions. We use fermions to clarify, sharpen, and extend the theory of set partition crossing resolution.
