On motives of parabolic Higgs bundles and parabolic connections

Sumit Roy

Let $X$ be a compact Riemann surface of genus $g \geq 2$ and let $D \subset X$ be a fixed finite subset. We considered the moduli spaces of parabolic Higgs bundles and of parabolic…

On torsion-freeness of Kähler differential sheaves

Nilkantha Das, Sumit Roy

Let $X$ be a normal algebraic variety over an algebraically closed field $k$ of characteristic zero. We prove that the Kähler differential sheaf of $X$ is torsion-free if and only…

Spectral data for parabolic projective symplectic/orthogonal Higgs bundles

Sumit Roy

Hitchin in [Duke Math. J. 54 (1), 91-114 (1987)] introduced a proper morphism from the moduli space of stable $G$ -Higgs bundles ($G=\mathrm{GL}(n,\mathbb{C}),\mathrm{Sp}(2m,\mathbb…

Picard group of moduli of parabolic Higgs bundles

Sumit Roy

Let $X$ be a compact Riemann surface of genus $g \geq 3$ and let $M_{par}$ be the moduli space of semistable parabolic bundles over $X$ . Let $\mathcal{M}_{\mathrm…

On birational Torelli theorems

Sumit Roy

Let $G$ be a simple simply-connected connected linear algebraic group over $C$ . We proved a $2$ -birational Torelli theorem for the moduli space of semistable principal $G$ …

Torelli theorem for the moduli space of symplectic parabolic Higgs bundles

Sumit Roy

Let $(X, D)$ and $(X^{'}, D^{'})$ be two compact Riemann surfaces of genus $g \geq 4$ with the set of marked points $D \subset X$ and $D^{'} \subset X^{'}$ . Fix a parabolic line bundle $L$ with…
