Arithmetically Cohen-Macaulay bundles on cubic threefolds

M Lahoz, E Macri, P Stellari - Algebraic Geometry, 2015 - air.unimi.it
Abstract We study arithmetically Cohen Macaulay bundles on cubic threefolds by using
derived category techniques. We prove that the moduli space of stable Ulrich bundles of any …

Instanton sheaves on complex projective spaces

M Jardim - arXiv preprint math/0412142, 2004 - arxiv.org
We study a class of torsion-free sheaves on complex projective spaces which generalize the
much studied mathematical instanton bundles. Instanton sheaves can be obtained as …

Stable Ulrich bundles

M Casanellas, R Hartshorne, F Geiss… - International journal of …, 2012 - World Scientific
The existence of stable ACM vector bundles of high rank on algebraic varieties is a
challenging problem. In this paper, we study stable Ulrich bundles (that is, stable ACM …

Moduli spaces of semistable sheaves on singular genus 1 curves

DH Ruipérez, ACL Martín, DS Gómez… - International …, 2009 - ieeexplore.ieee.org
We find some equivalences of the derived category of coherent sheaves on a Gorenstein
genus one curve that preserve the (semi)-stability of pure-dimensional sheaves. Using them …

On the semistability of instanton sheaves over certain projective varieties

M Jardim, RM Miró-Roig - Communications in Algebra®, 2008 - Taylor & Francis
We show that instanton bundles of rank r≤ 2 n− 1, defined as the cohomology of certain
linear monads, on an n-dimensional projective variety with cyclic Picard group are …

D Huybrechts, M Lehn - 2010 - books.google.com
Now back in print, this highly regarded book has been updated to reflect recent advances in
the theory of semistable coherent sheaves and their moduli spaces, which include moduli …

On a compactification of a moduli space of stable vector bundles on a rational surface

M MARUYAMA - Algebraic geometry and commutative algebra, 1988 - Elsevier
Publisher Summary This chapter highlights a compactification of a moduli space of stable
vector bundles on a rational surface. It discusses semi-stable sheaves, semi-stable sheaves …

Bridgeland stability of minimal instanton bundles on Fano threefolds

X Qin - Journal of the Mathematical Society of Japan, 2023 - jstage.jst.go.jp
We prove that minimal instanton bundles on a Fano threefold x of Picard rank one and index
two are semistable objects in the Kuznetsov component Ku (x), with respect to the stability …

Stable rank-2 bundles on Calabi–Yau manifolds

WP Li, Z Qin - International Journal of Mathematics, 2003 - World Scientific
In this paper, we apply the technique of chamber structures of stability polarizations to
construct the full moduli space of rank-2 stable sheaves with certain Chern classes on …

Principal bundles on projective varieties and the Donaldson-Uhlenbeck compactification

V Balaji - Journal of Differential Geometry, 2007 - projecteuclid.org
Let $ H $ be a semisimple algebraic group. We prove the semistable reduction theorem for
$\mu $-semistable principal $ H $-bundles over a smooth projective variety $ X $ defined …
