Faithful action of braid group on bosonic extensions
Published 3 Dec 2025 in math.RT and math.QA | (2512.03425v1)
Abstract: The braid group action on the bosonic extension of the quantum group has been introduced in recent works, and it can be regarded as a generalization of Lusztig's symmetries on the quantum group. In this notes, we prove the faithfulness of this braid group action.
