    • Moduli Spaces of Reflexive Sheaves of Rank 2 

      Kleppe, Jan Oddvar (Canadian Journal of Mathematics;62 (5), Journal article; Peer reviewed, 2010)
      Let F be a coherent rank 2 sheaf on a scheme Y in P^n of dimension at least two. In this paper we study the relationship between the functor which deforms a pair (F,s), s in H^0(F), and the functor which deforms the ...
