Abstract
We show that whenever a physical system is composed of two subsystems, there exists a (σ1,σ2) ‐linear map between their generalized Hilbert spaces which describes this composition. As a consequence, subsystems of a physical system described by a generalized Hilbert space over a division ring K are always described by a generalized Hilbert space over a subdivision ring of K.Keywords
