The conjecture for

D Maulik, J Shen - Annals of Mathematics, 2024 - projecteuclid.org
We prove the P=W conjecture for GL_n for all ranks n and curves of arbitrary genus g≥2.
The proof combines a strong perversity result on tautological classes with the curious Hard …

Cohomological χ–independence for moduli of one-dimensional sheaves and moduli of Higgs bundles

D Maulik, J Shen - Geometry & Topology, 2023 - msp.org
We prove that the intersection cohomology (together with the perverse and the Hodge
filtrations) for the moduli space of one-dimensional semistable sheaves supported in an …

Global critical chart for local Calabi–Yau threefolds

T Kinjo, N Masuda - International Mathematics Research Notices, 2024 - academic.oup.com
In this paper, we investigate Keller's deformed Calabi–Yau completion of the derived
category of coherent sheaves on a smooth variety. In particular, for an-dimensional smooth …

Unramified covers and branes on the Hitchin system

E Franco, PB Gothen, A Oliveira, A Peón-Nieto - Advances in Mathematics, 2021 - Elsevier
We study the locus of the moduli space of GL (n, C)-Higgs bundles on a curve given by
those Higgs bundles obtained by pushforward under a connected unramified cover. We …

On the P = W conjecture for

MA de Cataldo, D Maulik, J Shen - Selecta Mathematica, 2022 - Springer
Let p be a prime number. We prove that the P= W conjecture for SL p is equivalent to the P=
W conjecture for GL p. As a consequence, we verify the P= W conjecture for genus 2 and SL …

Algebraic cycles and Hitchin systems

D Maulik, J Shen, Q Yin - arXiv preprint arXiv:2407.05177, 2024 - arxiv.org
The purpose of this paper is to study motivic aspects of the Hitchin system for $\mathrm {GL}
_n $. Our results include the following.(a) We prove the motivic decomposition conjecture of …

Topological K-theory of quasi-BPS categories for Higgs bundles

T Pădurariu, Y Toda - arXiv preprint arXiv:2409.10800, 2024 - arxiv.org
In a previous paper, we introduced quasi-BPS categories for moduli stacks of semistable
Higgs bundles. Under a certain condition on the rank, Euler characteristic, and weight, the …

Lie algebroid connections, twisted Higgs bundles and motives of moduli spaces

D Alfaya, A Oliveira - Journal of Geometry and Physics, 2024 - Elsevier
Abstract Let L=(L,[⋅,⋅], δ) be an algebraic Lie algebroid over a smooth projective curve X of
genus g≥ 2 such that L is a line bundle whose degree is less than 2− 2 g. Let r and d be …

Complex K-theory of moduli spaces of Higgs bundles

M Groechenig, S Shen - arXiv preprint arXiv:2212.10695, 2022 - arxiv.org
We establish an isomorphism of complex $ K $-theory of the moduli space $\check {\mathcal
{M}} $ of $``SL_n" $-Higgs bundles of degree $ d $ and rank $ n $(in the sense of Hausel …
