Cohomological gauge theory, quiver matrix models and Donaldson–Thomas theory

M Cirafici, A Sinkovics, RJ Szabo - Nuclear physics B, 2009 - Elsevier
We study the relation between Donaldson–Thomas theory of Calabi–Yau threefolds and a
six-dimensional topological Yang–Mills theory. Our main example is the topological U (N) …

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 …

New divisors in the boundary of the instanton moduli space

M Jardim, D Markushevich, AS Tikhomirov - arXiv preprint arXiv …, 2015 - arxiv.org
Let ${\mathcal I}(n) $ denote the moduli space of rank $2 $ instanton bundles of charge $ n $
on ${\mathbb P}^ 3$. We know from several authors that ${\mathcal I}(n) $ is an irreducible …

ADHM construction of perverse instanton sheaves

AA Henni, M Jardim, RV Martins - Glasgow Mathematical Journal, 2015 - cambridge.org
We present a construction of framed torsion free instanton sheaves on a projective variety
containing a fixed line which further generalises the one on projective spaces. This is done …

Moduli of autodual instanton bundles

M Jardim, S Marchesi, A Wissdorf - Bulletin of the Brazilian Mathematical …, 2016 - Springer
We provide a description of the moduli space of framed autodual instanton bundles on
projective space, focusing on the particular cases of symplectic and orthogonal instantons …

[HTML][HTML] The ADHM variety and perverse coherent sheaves

M Jardim, RV Martins - Journal of Geometry and Physics, 2011 - Elsevier
We study the full set of solutions to the ADHM equation as an affine algebraic set, the ADHM
variety. We determine a filtration of the ADHM variety into subvarieties according to the …

Moduli spaces of framed instanton bundles on CP3 and twistor sections of moduli spaces of instantons on C2

M Jardim, M Verbitsky - Advances in Mathematics, 2011 - Elsevier
We show that the moduli space M of framed instanton bundles on CP 3 is isomorphic (as a
complex manifold) to a subvariety in the moduli of rational curves of the twistor space of the …

Biquaternions and ADHM construction of non-compact SL (2, C) Yang–Mills instantons

SH Lai, JC Lee, IH Tsai - Annals of Physics, 2015 - Elsevier
We extend quaternion calculation in the ADHM construction of S p (1)(= SU (2)) self-dual
Yang–Mills (SDYM) instantons to the case of biquaternion. We use the biconjugate …

Hilbert schemes, commuting matrices and hyperkähler geometry

R Bielawski, C Peternell - Journal of the London Mathematical …, 2022 - Wiley Online Library
We represent algebraic curves via commuting matrix polynomials. This allows us to show
that the Hilbert scheme of cohomologically stable non‐planar curves of genus 0 and degree …
