The Gorenstein property for projective coordinate rings of the moduli of parabolic ${\mathrm{SL}}_2$-principal bundles on a smooth curve

Theodore Faust, Christopher Manon

Using combinatorial methods, we determine that a projective coordinate ring of the moduli of parabolic principal ${\mathrm{SL}}_2$-bundles on a marked projective curve is not Gorenst…
