Let $(\mathbf{U},\mathbf{U}^{\imath})$ be an iquantum group of finite type, where $\mathbf{U}^{\imath}$ is the coideal subalgebra of a Drinfeld–Jimbo quantum group $\mathbf{U}$ ass…

Let $\mathfrak{U}^\imath$ be the 2-category categorifying the quasi-split iquantum group in the general setup, allowing symmetrizable Cartan matrices and general choices of the pol…
