Brauer group of punctual Quot scheme of points on a smooth projective surface

A. J. Parameswaran, Yashonidhi Pandey

Let $X$ be a smooth projective surface over an algebraically closed field $k$ such that $c ha r (k) \neq = 2$ . Let $X^{[d]}$ denote the punctual Hilbert scheme of zero dimensional quoti…

Etale Fundamental group of moduli of torsors under Bruhat-Tits group scheme over a curve

A. J. Parameswaran, Yashonidhi Pandey

Let $X$ be a smooth projective curve over an algebraically closed field $k$ . Let $G$ be a Bruhat-Tits group scheme on $X$ which is generically semi-simple and trivial. We…

Character on a homogeneous space

A. J. Parameswaran, Amith Shastri K

In this paper we look at the notion of cohomological triviality of fibrations of homogeneous spaces of affine algebraic groups defined over $C$ and use topological methods…
