    • Brill–Noether loci on moduli spaces of symplectic bundles over curves 

      Hitching, George Harry; Bajravani, Ali (Collectanea Mathematica;, Journal article; Peer reviewed, 2020-11-20)
      The symplectic Brill–Noether locus Sk 2n,K associated to a curve C parametrises stable rank 2n bundles over C with at least k sections and which carry a nondegenerate skewsymmetric bilinear form with values in the canonical ...

    • Comparison theorems for deformation functors via invariant theory 

      Christophersen, Jan Arthur; Kleppe, Jan Oddvar (Collectanea Mathematica;January 2019, Volume 70, Issue 1, Journal article; Peer reviewed, 2018-09-06)
      We compare deformations of algebras to deformations of schemes in the setting of invariant theory. Our results generalize comparison theorems of Schlessinger and the second author for projective schemes. We consider ...
