The study established an isomorphism between the moduli space of framed flags of sheaves on the projective plane and stable representations of a certain quiver. The weaker claim regarding the existence of unobstructed points in the quiver moduli space replaces one of the previous claims. Additionally, the research extends some results regarding the maximal stability chamber and the perfect obstruction theory for the quiver moduli space from the cited paper.
In a previous paper, the first two named authors established an isomorphism between the moduli space of framed flags of sheaves on the projective plane and the moduli space of stable representations of a certain quiver. In the present note, we substitute one of the claims made, namely [5, Theorem 17], for a weaker claim regarding the existence of unobstructed points in the quiver moduli space. We also extend some of the results of the cited paper, concerning the maximal stability chamber within which the isomorphism mentioned holds, and the existence of a perfect obstruction theory for the quiver moduli space.
