Brauer and Picard groups of moduli spaces of parabolic vector bundles on a real curve (2303.05414v1)

Abstract: We determine the Brauer group and Picard group of the moduli space $U^{' s}_{L,par}$ of stable parabolic vector bundles of rank $r$ with determinant $L$ on a real curve $Y$ of arithmetic genus $g \,\ge\, 2$ with at most nodes as singularities.
