Higher genus Angel surfaces

Rivu Bardhan, Indranil Biswas, Shoichi Fujimori +1

We prove the existence of complete minimal surfaces in $R^{3}$ of arbitrary genus $p \geq 1$ and least total absolute curvature with precisely two ends -- one catenoidal…

Fixed points and Holomorphic Structures on Line Bundles over the Quantum Projective Line

Indranil Biswas, Satyajit Guin, Pradip Kumar

It has recently been observed that, in contrast to the classical case, holomorphic structures on line bundles over the quantum projective line are not uniquely determined by degree…

Brauer group of moduli stacks of parabolic principal bundles over a curve

Indranil Biswas, Sujoy Chakraborty

We prove that the Brauer group of the moduli stack of parabolic stable principal $PGL (r, C)$ -bundles on a curve $X$ , for a generic system of weights along an arbitra…

Brauer group of moduli of parabolic symplectic bundles

Indranil Biswas, Sujoy Chakraborty, Arijit Dey

Let $X$ be a smooth connected complex projective curve of genus $g$ , with $g \geq 3$ . Fix an integer $r \geq 2$ , a finite subset $D \subset X$ , and a line bundle $L$ on $X$ .…

Parabolic vector bundles and Lie algebroid connections

David Alfaya, Indranil Biswas, Pradip Kumar +1

Given a holomorphic Lie algebroid on an m-pointed Riemann surface, we define parabolic Lie algebroid connections on any parabolic vector bundle equipped with parabolic structure ov…

Holomorphic Lie algebroid connections on holomorphic principal bundles on compact Riemann surfaces

Indranil Biswas

For a $I^$ --equivariant holomorphic Lie algebroid $(V, I ¨ )$ , on a compact Riemann surface $X$ equipped with an action of a finite group $I^$ , we investigate the equivariant holom…
