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 RR with filtration FRFR and subring S=F0RS = F_0R. Nice examples appear for chains of groups, chains of Lie algebras, rings of differential operators on some variety or VV-gliders for WW for algebraic varieties VV and WW. 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 Proj R\mathrm{Proj}~ R (e.g. for some P.I. ring RR) in terms of prime ideals, RR-tors in terms of torsion theories and W(R)\underline{\mathcal{W}}(R) in terms of a noncommutative Grothendieck topology based on words of Ore set localizations.
