Classification of irreducible modules in a Schur–Weyl category

Let SW(V){\cal SW}(V) be the Schur–Weyl category, let VλV_{\lambda} denote its distinguished objects, and let g=sl(VS){\bf g}=sl(V_S) act on these objects. A linear map between two objects of SW(V){\cal SW}(V) is an sl(VS)sl(V_S)-morphism when it commutes with this action. The Schur–Weyl module classification conjecture. All the g{\bf g}-modules VλV_{\lambda} are irreducible, every irreducible finite-dimensional g{\bf g}-module is isomorphic to one of them, and a linear map between two objects of SW(V){\cal SW}(V) is a morphism in the category exactly when it is an sl(VS)sl(V_S)-morphism. Thus the category SW(V){\cal SW}(V) should be treatable as the category of sl(VS)sl(V_S)-modules, or equivalently of U(sl(VS))U(sl(V_S))-modules. The statement proposes an identification of the Schur–Weyl category with the finite-dimensional representation category of the twisted Lie algebra; the supplied text does not establish the classification or indicate its resolution.
