Lorentz groups of cyclotomic extensions
Vadim Schechtman
In this (mostly historical) note we show how a unified Kummer-Artin-Schreier sequence from [W], [SOS] may be recovered from the relativistic velocity addition law.
Witt ring localized
Vadim Schechtman
The rings of -typical Witt vectors are interpreted as spaces of vanishing cycles for some perverse sheaves over a disc. This allows to "localize"\ an isomorphism emerging in Dri…

Vassily Gorbounov, Vadim Schechtman
In the work of Mukhin and Varchenko from 2002 there was introduced a Wronskian map from the variety of full flags in a finite dimensional vector space into a product of projective…
