Moduli spaces of framed sheaves and quiver varieties (vol 118, pg 20, 2017)

[摘要] This paper is an erratum to our paper Moduli spaces of framed sheaves and quiver varieties (j.Geom. Phys., 2016). As a byproduct, we prove a result (Prop. 2.5) providing a description of the fibre T-V Gr(a, r)(circle plus n-1), for each V is an element of Gr(a, r), as the space of isomorphism classes of certain extensions of sheaves on Hirzebruch surfaces.
