Abstract: We introduce an $ \mathfrak{sl}_n$ homology theory for knots and links in the thickened annulus. To do so, we first give a fresh perspective on sutured annular Khovanov homology, showing that its definition follows naturally from trace decategorifications of enhanced $ \mathfrak{sl}_{2}$ foams and categorified quantum $ \mathfrak{gl}_m$, via classical skew Howe duality. This framework then extends to give our annular $ \mathfrak{sl}_n$ link homology theory, which we call sutured annular Khovanov-Rozansky homology. We show that the $ \mathfrak{sl}_n$ sutured annular Khovanov-Rozansky homology of an annular link carries an action of the Lie algebra $ \mathfrak{sl}_n$, which in the $ n=2$ case recovers a result of Grigsby-Licata-Wehrli.
