$A^{1}$ --connectedness of moduli stack of semi-stable and parabolic semi-stable vector bundles over a curve

Sujoy Chakraborty, Saurav Holme Choudhury

Let $C$ be an irreducible smooth projective curve of genus $g \geq 2$ over an algebraically closed field. We prove that the moduli stack of semi-stable vector bundles on $C$ of fixe…

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…

Private key and password protection by steganographic image encryption

Debesh Choudhury, Sujoy Chakraborty

We propose a technique to protect and preserve a private key or a passcode in an encrypted two-dimensional graphical image. The plaintext private key or the passcode is converted i…

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 $X$ .…
