Affine and Cyclotomic Schur Categories

Abstract Using the affine web category introduced in a prequel as a building block, we formulate a diagrammatic $$\Bbbk $$ k -linear monoidal category, the affine Schur category , for any commutative ring $$\Bbbk $$ k . We then formulate the cyclotomic Schur categories . Integral...
