Query: On Verlinde sheaves and strange duality over elliptic Noether-Lefschetz
  divisors   We extend results on generic strange duality for K3 surfaces by showing that
the proposed isomorphism holds over an entire Noether-Lefschetz divisor in the
moduli space of quasipolarized K3s. We interpret the statement globally as an
isomorphism of sheaves over this divisor, and also describe the global
construction over the space of polarized K3s.
