Weil representations of twisted loop groups of type $A_n^{(2)}$ (2111.09018v2)
Published 17 Nov 2021 in math.RT
Abstract: We construct Weil representations of twisted loop groups of type $A_n{(2)}$ over local fields. We prove that the associated cover of the twisted loop group is the two fold metaplectic cover of the affine Kac-Moody group of type $A_n{(2)}$ given by Patnaik-Puskas.
