Cohomological -independence for Higgs bundles and Gopakumar–Vafa invariants

T Kinjo, N Koseki - Journal of the European Mathematical Society, 2024 - ems.press
The aim of this paper is two-fold. Firstly, we prove Toda's-independence conjecture for
Gopakumar–Vafa invariants of arbitrary local curves. Secondly, following Davison's work, we …

Stable maps to Looijenga pairs

P Bousseau, A Brini, M van Garrel - arXiv preprint arXiv:2011.08830, 2020 - arxiv.org
A log Calabi-Yau surface with maximal boundary, or Looijenga pair, is a pair $(Y, D) $ with $
Y $ a smooth rational projective complex surface and $ D= D_1+\dots+ D_l\in|-K_Y| $ an …

Moduli stacks of quiver bundles with applications to Higgs bundles

M Azam, S Rayan - arXiv preprint arXiv:2407.11958, 2024 - arxiv.org
We provide a general method for constructing moduli stacks whose points are diagrams of
vector bundles over a fixed base, indexed by a fixed simplicial set--that is, quiver bundles of …

Non-Abelian Hodge theory and related topics

P Huang - SIGMA. Symmetry, Integrability and Geometry: Methods …, 2020 - emis.de
This paper is a survey aimed on the introduction of non-Abelian Hodge theory that gives the
correspondence between flat bundles and Higgs bundles. We will also introduce some …

Moduli spaces of generalized hyperpolygons

S Rayan, LP Schaposnik - The Quarterly Journal of Mathematics, 2021 - academic.oup.com
We introduce the notion of generalized hyperpolygon, which arises as a representation, in
the sense of Nakajima, of a comet-shaped quiver. We identify these representations with …

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 …

P= W phenomena in algebraic and enumerative geometry

C Felisetti - Bollettino dell'Unione Matematica Italiana, 2024 - Springer
In view of the recent proofs of the P= W conjecture, the present paper reviews and relates
the latest results in the field, with a view on how P= W phenomena appear in multiple areas …

Some natural extensions of the parking space

M Konvalinka, V Tewari - Journal of Combinatorial Theory, Series A, 2021 - Elsevier
We construct a family of S n modules indexed by c∈{1,…, n} with the property that upon
restriction to S n− 1 they recover the classical parking function representation of Haiman …

Very stable and wobbly loci for elliptic curves

K Banerjee, S Rayan - arXiv preprint arXiv:2411.06335, 2024 - arxiv.org
We explore very stable and wobbly bundles, twisted in a particular sense by a line bundle,
over complex algebraic curves of genus $1 $. We verify that twisted stable bundles on an …
