Logarithmic spectral correspondence for $V$ --twisted Higgs bundles on punctured curves

Pradip Kumar

Let $X$ be a smooth projective complex curve, $P \subset X$ a reduced effective divisor, and $X^{0} = X ∖ P$ . We study logarithmic $V$ -twisted Higgs bundles arising from a loga…

Lie algebroid connection and Harder-Narasimhan reduction

Ashima Bansal, Indranil Biswas, Pradip Kumar

Take a holomorphic Lie algebroid $(V, ϕ)$ on a compact connected Riemann surface $X$ such that the anchor map $ϕ$ is not surjective. Let $P$ be a parabolic subgroup of a complex…

A criterion for holomorphic Lie algebroid connections

David Alfaya, Indranil Biswas, Pradip Kumar +1

Given a holomorphic Lie algebroid $(V, ϕ)$ on a compact connected Riemann surface $X$ , we give a necessary and sufficient condition for a holomorphic vector bundle $E$ on $X$ to ad…

Remarks on Higgs bundles twisted by a vector bundle

David Alfaya, Indranil Biswas, Pradip Kumar

For any V-twisted Higgs bundle on a compact Riemann surface X, where V is a holomorphic vector bundle of rank two on X, there are two associated Higgs bundles on X, twisted by line…

A criterion for Lie algebroid connections on a compact Riemann surface

Indranil Biswas, Pradip Kumar, Anoop Singh

Let $X$ be a compact connected Riemann surface and $(V, ϕ)$ a holomorphic Lie algebroid on $X$ such that the holomorphic vector bundle $V$ is stable. We give a necessary and suffic…
