Towers of torsors over a field

Marco Antei, Indranil Biswas, Michel Emsalem

Let be a projective, connected and smooth scheme defined over an algebraically closed field . In this paper we prove that a tower of finite torsors (i.e., under the action o…

Models of torsors and the fundamental group scheme

Marco Antei, Michel Emsalem

Given a relative faithfully flat pointed scheme over the spectrum of a discrete valuation ring this paper is motivated by the study of the natural morphism from the funda…

The pseudo-fundamental group-scheme

Marco Antei, Arijit Dey

Let be any scheme defined over a Dedekind scheme with a given section . We prove the existence of a pro-finite -group scheme and a universal $\a…
