Categorification of quasi-split iquantum groups (2505.22929v1)
Published 28 May 2025 in math.QA and math.RT
Abstract: We introduce a new family of graded 2-categories generalizing the 2-quantum groups introduced by Khovanov, Lauda and Rouquier. We use them to categorify quasi-split iquantum groups in all symmetric types.
