چکیده
In order to study wall crossing formula of Donaldson type invariants on the blown-up plane, Nakajima-Yoshioka constructed a sequence blow-up/blow-down diagrams connecting moduli space torsion free framed sheaves projective and that its blow-up. this paper, we prove Nakajima-Yoshioka's diagram realizes minimal model program. Furthermore, obtain fully-faithful embedding between derived categories these spaces.

Birational Geometry of Moduli Spaces of Sheaves and Bridgeland Stability
Moduli spaces of sheaves and Hilbert schemes of points have experienced a recent resurgence in interest in the past several years, due largely to new techniques arising from Bridgeland stability conditions and derived category methods. In particular, classical questions about the birational geometry of these spaces can be answered by using new tools such as the positivity lemma of Bayer and Mac...
متن کاملLectures on perverse sheaves on instanton moduli spaces
Let G be an almost simple simply-connected algebraic group over C with the Lie algebra g. Let h be a Cartan subalgebra of g. We assume G is of type ADE, as there arise technical issues for type BCFG. (We will remark them at relevant places. See footnotes 5, 12.) At some points, particularly in this introduction, we want to include the case G = GL(r). We will not make clear distinction between t...
متن کاملThe Birational Geometry of the Moduli Spaces of Sheaves on P2
In this paper, we survey recent developments in the birational geometry of the moduli spaces M(ξ) of semistable sheaves on P following [ABCH], [CH], [CH2], [CHW] and [H]. We discuss the cones of effective, ample and movable divisors on M(ξ). We introduce Bridgeland stability conditions, the main technical tools that precipitated the recent advances, and explain their applications to interpolati...
متن کاملOn the Birational Geometry of Moduli Spaces of Pointed Curves
We prove that the moduli space Mg,n of smooth curves of genus g with n marked points is rational for g = 6 and 1 ≤ n ≤ 8, and it is unirational for g = 8 and 1 ≤ n ≤ 11, g = 10 and 1 ≤ n ≤ 3, g = 12 and n = 1. 0. Introduction and notation LetMg,n be the (coarse) moduli space of smooth curves of genus g with nmarked points defined over the field C of complex numbers and Mg,n its Deligne–Mumford ...
متن کاملBirational Geometry of Singular Moduli Spaces of O’grady Type
Following Bayer and Macr̀ı, we study the birational geometry of singular moduli spaces M of sheaves on a K3 surface X which admit symplectic resolutions. More precisely, we use the Bayer-Macr̀ı map from the space of Bridgeland stability conditions Stab(X) to the cone of movable divisors on M to relate wall-crossing in Stab(X) to birational transformations of M . We give a complete classification ...
