چکیده
We study relations between the quadraticity of Kuranishi family a coherent sheaf on complex projective scheme and formality DG-Lie algebra its derived endomorphisms. In particular, we prove that for polystable smooth surface endomorphisms is formal if only quadratic.

Noncommutative Deformations of Sheaves of Modules
Let k be an algebraically closed field, let X be a topological space, let A be a sheaf of associative k-algebras on X, and let F = {F1, . . . ,Fp} be a finite family of sheaves of left A-modules on X. In this paper, we develop a noncommutative deformation theory for the family F . This theory generalizes the noncommutative deformation theory for finite families of left modules over an associati...
متن کاملModuli of Sheaves on Blown-up Surfaces
connection with the so-called S-duality conjecture of Vafa-Witten. In fact, it is already known that there are explicit \universal" relations between invariants which are independent of the surface X. It is due to Yoshioka [9], under the assumption that moduli spaces are nonsingular projective varieties. His proof uses an ingenious trick, unstable sheaves. Although the proof give us the univers...
متن کاملMaps, Sheaves, and K3 Surfaces
The conjectural equivalence of curve counting on Calabi-Yau 3-folds via stable maps and stable pairs is discussed. By considering Calabi-Yau 3-folds with K3 fibrations, the correspondence naturally connects curve and sheaf counting on K3 surfaces. New results and conjectures (with D. Maulik) about descendent integration on K3 surfaces are announced. The recent proof of the Yau-Zaslow conjecture...
متن کاملConstrained deformations based on convolution surfaces
Deformation is a powerful tool for shape modeling and computer animation. In this paper we present a new local deformation model based on convolution surfaces. After a user specifies a series of constraints, which can consist of line segments, arcs and quadratic curves, their effective radii and maximum displacements, the deformation model creates a set of convolution surfaces taking the constr...
متن کاملSemi-homogeneous Sheaves, Fourier-mukai Transforms and Moduli of Stable Sheaves on Abelian Surfaces
This paper studies stable sheaves on abelian surfaces of Picard number one. Our main tools are semi-homogeneous sheaves and Fourier-Mukai transforms. We introduce the notion of semi-homogeneous presentation and investigate the behavior of stable sheaves under Fourier-Mukai transforms. As a consequence, an affirmative proof is given to the conjecture proposed by Mukai in the 1980s. This paper al...
