On the classification of products of Hilbert schemes of points over a surface

Arijit Dey, Arijit Mukherjee, Anubhab Pahari

Let $S$ be a smooth projective surface over $C$ and $S^{[n]}$ be the Hilbert scheme of $n$ points over $S$ , for any positive integer $n$ . Let $a = (n_{1}, \dots, n_{r})$ an…

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 $X$ .…

Brauer group of moduli stack of parabolic $PSp (r, C)$ --bundles over a curve

Indranil Biswas, Sujoy Chakraborty, Arijit Dey

Take an irreducible smooth complex projective curve $X$ of genus $g$ , with $g \geq 3$ . Let $r$ be an even positive integer. We prove that the Brauer group of the moduli stack of…

Statistics of Moduli Spaces of vector bundles over hyperelliptic curves

Arijit Dey, Sampa Dey, Anirban Mukhopadhyay

We give an asymptotic formula for the number of $F_{q}$ -rational points over a fixed determinant moduli space of stable vector bundles of rank $r$ and degree $d$ over a sm…

Chen--Ruan cohomology and orbifold Euler characteristic of moduli spaces of parabolic bundles

Indranil Biswas, Sujoy Chakraborty, Arijit Dey

We consider the moduli space of stable parabolic Higgs bundles of rank $r$ and fixed determinant, and having full flag quasi-parabolic structures over an arbitrary parabolic diviso…
