[HTML][HTML] A Kobayashi–Hitchin correspondence for I±-holomorphic bundles

S Hu, R Moraru, R Seyyedali - Advances in Mathematics, 2016 - Elsevier
In this paper, we introduce the notions of α-Hermitian–Einstein metric and α-stability for I±-
holomorphic vector bundles on bi-Hermitian manifolds. Moreover, we establish a Kobayashi …

Topological recursion and variations of spectral curves for twisted Higgs bundles

C Mahadeo, S Rayan - arXiv preprint arXiv:2401.06694, 2024 - arxiv.org
Prior works relating meromorphic Higgs bundles to topological recursion, in particular those
of Dumitrescu-Mulase, have considered non-singular models that allow the recursion to be …

Moduli spaces of semistable rank-2 co-Higgs bundles over

AV Colmenares - The Quarterly journal of mathematics, 2017 - academic.oup.com
It has been observed, by Rayan, that the complex projective surfaces that potentially admit
non-trivial examples of semistable co-Higgs bundles must be found at the lower end of the …

Twisted cyclic quiver varieties on curves

S Rayan, E Sundbo - European Journal of Mathematics, 2021 - Springer
We study the algebraic geometry of twisted Higgs bundles of cyclic type along complex
curves. These objects, which generalize ordinary cyclic Higgs bundles, can be identified …

[图书][B] Quadratic Poisson brackets and co-Higgs fields

M Matviichuk - 2020 - search.proquest.com
This thesis is devoted to studying the geometry of holomorphic Poisson brackets on complex
manifolds. We concentrate on the case when the underlying manifold admits a structure of a …

Rank two nilpotent co-Higgs sheaves on complex surfaces

M Corrêa - Geometriae dedicata, 2016 - Springer
Abstract Let (E, ϕ)(E, ϕ) be a rank two co-Higgs vector bundles on a Kähler compact surface
X with ϕ ∈ H^ 0 (X, End (E) ⊗ T_X) ϕ∈ H 0 (X, E nd (E)⊗ TX) nilpotent. If (E, ϕ)(E, ϕ) is …

[HTML][HTML] Moduli spaces of Λ-modules on abelian varieties

E Franco, P Tortella - Advances in Mathematics, 2017 - Elsevier
We study the moduli space MX (Λ, n) of semistable Λ-modules of vanishing Chern classes
over an abelian variety X, where Λ belongs to a certain subclass of D-algebras. In particular …

[HTML][HTML] Canonical metrics on holomorphic bundles over compact bi-Hermitian manifolds

P Zhang - Journal of Geometry and Physics, 2019 - Elsevier
The purpose of this paper is twofold. We first solve the Dirichlet problem for α-Hermitian–
Einstein equations on I±-holomorphic bundles over bi-Hermitian manifolds. Second, by …
