Abstract |
|
Motivated by Heisenberg’s picture of quantum dynamics the notion of a velocity map is introduced and its properties are investigated. The main theorem in the present exposition strengthens the well-known result that every derivation on the algebra of all bounded operators on a complex separable Hilbert space is inner. A constructive proof leads to an inversion formula for the observables inducing the derivation. |
