By
\mathbb{S}-module, we mean an \mathbb{S}-object in the category \mathsf{Vect} of finite-dimensional vector spaces over a field
k of characteristic zero (the symmetric groups act from the right by convention). Then each \mathbb{S}-module determines a
Schur functor on \mathsf{Vect}. This definition of \mathbb{S}-module shares its name with the considerably better-known model for
highly structured ring spectra due to Elmendorf, Kriz, Mandell and May. == See also ==
