Localization and sheaves of glider representations
Abstract
The notion of a glider representation of a chain of normal subgroups of a group is defined by a new structure, i.e. a fragment for a suitable filtration on the group ring. This is a special case of general glider representations defined for a positively filtered ring with filtration and subring . Nice examples appear for chains of groups, chains of Lie algebras, rings of differential operators on some variety or -gliders for for algebraic varieties and . This paper aims to develop a scheme theory for glider representations via the localizations of filtered modules. With an eye to noncommutative geometry we allow schemes over noncommutative rings with particular attention to so-called almost commutative rings. We consider particular cases of (e.g. for some P.I. ring ) in terms of prime ideals, -tors in terms of torsion theories and in terms of a noncommutative Grothendieck topology based on words of Ore set localizations.
