Quot-scheme limit of Fubini-Study metrics and Donaldson's functional for vector bundles [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
For a holomorphic vector bundle $E$ over a polarised K\"ahler manifold, we establish a direct link between the slope stability of $E$ and the asymptotic behaviour of Donaldson's functional, by defining the Quot-scheme limit of Fubini-Study metrics.

Kobayashi—Hitchin correspondence for twisted vector bundles

open access: yesComplex Manifolds, 2021
We prove the Kobayashi—Hitchin correspondence and the approximate Kobayashi—Hitchin correspondence for twisted holomorphic vector bundles on compact Kähler manifolds.

Polystable bundles and representations of their automorphisms

open access: yesComplex Manifolds, 2022
Using a quasi-linear version of Hodge theory, holomorphic vector bundles in a neighbourhood of a given polystable bundle on a compact Kähler manifold are shown to be (poly)stable if and only if their corresponding classes are (poly)stable in the sense of

Uniform L2-estimates for flat nontrivial line bundles on compact complex manifolds

open access: yesComplex Manifolds
In this study, we extend the uniform L2{L}^{2}-estimate of ∂¯\bar{\partial }-equations for flat nontrivial line bundles, proved for compact Kähler manifolds by Hashimoto and Koike, to compact complex manifolds.
