Abstract:

The theory of Schur functors provides a powerful and elegant approach to the representation theory of $\mathbf {GL}_n$—at least to the so-called polynomial representations—especially to questions about how the theory varies with $n$. We develop parallel theories that apply to other classical groups and to nonpolynomial representations of $\mathbf {GL}_n$. These theories can also be viewed as linear analogs of the theory of $\mathbf {FI}$-modules.
