    • Isotropic Quot schemes of orthogonal bundles over a curve 

      Choe, Insong; Cheong, Daewoong; Hitching, George Harry (International Journal of Mathematics;, Peer reviewed; Journal article, 2021-05-19)
      We study the isotropic Quot schemes IQe(V ) parameterizing degree e isotropic subsheaves of maximal rank of an orthogonal bundle V over a curve. The scheme IQe(V ) contains a compactification of the space IQe◦(V ) of degree ...

    • Quot schemes, Segre invariants, and inflectional loci of scrolls over curves 

      Hitching, George Harry (Geometriae Dedicata;, Journal article; Peer reviewed, 2019-06-26)
      Let E be a vector bundle over a smooth curve C, and S = PE the associated projective bundle. We describe the inflectional loci of certain projective models ψ: S 99K Pn in terms of Quot schemes of E. This gives a geometric ...
