Smooth locus of twisted affine Schubert varieties and twisted affine Demazure modules

Let ${\mathscr {G}} $ be a special parahoric group scheme of twisted type over the ring of formal power series over $\mathbb {C}$ , excluding the absolutely special case of $A^{(2)}_{2\ell }$ . Using the methods and results of Zhu, we prove a duality theorem for general ${\mat...
