On Homomorphisms of Algebras Generated by Projectors and Coxeter Functors

  • Published:
Ukrainian Mathematical Journal Aims and scope

Abstract

We consider algebras generated by idempotents in Banach spaces and orthoprojectors in Hilbert spaces whose sum is a multiple of the identity. We construct several functors generated by homomorphisms of the algebras considered between categories of representations. We investigate properties of these functors and present their applications.
