A \(q\)-analogue of the Weyl-Kac denominator formulas of types \(\widetilde F_{41}\) and \(\widetilde G_{21}\). (English) Zbl 1155.16301
Summary: By using Frobenius maps and \(F\)-stable representations, we give a \(q\)-analogue of the Weyl-Kac denominator formulas of types \(\widetilde F_{41}\) and \(\widetilde G_{21}\).
