On homomorphisms of $π_{1} (P^{1} - R)$ into compact semisimple groups

Vikraman Balaji, Yashonidhi Pandey

The aim of this paper is to give verifiable criteria for the existence of {\em irreducible} homomorphisms of $π_{1} (P^{1} - R)$ into compact semisimple groups, for a…

On a "Wonderful" Bruhat-Tits group scheme

V. Balaji, Y. Pandey

In this note we make a universal construction of Bruhat-Tits group scheme on wonderful embeddings of adjoint groups in the absolute and relative settings and of adjoint Kac-Moody g…

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…
