Die Katalytische Aktivierung des Schwefelsctionals of finite-dimensional representations and faithful representations are constructed. Topological tensor algebras such as the field algebra of quantum field theory and corresponding continuous representations are developed.

Each integrable representation of a finitely generated commutative unital .-algebra is expressed in terms of spectral integrals with respect to some spectral measure. An application to moment functionals is given.

We develop this theory in detail for representations that are induced from hermitian characters of commutative .-subalgebras. The Bargmann–Fock representation of the Weyl algebra is obtained in this manner.

https://doi.org/10.1007/978-3-642-48579-4 this chapter we develop three general methods (group graded .-algebras, fraction algebras, compatible pairs) and apply them to the representations of the Weyl algebra and enveloping algebras of finite-dimensional Lie algebras.

Basic notions (positive linear functionals, states, characters, quadratic modules) are introduced and investigated. The Gleason–Kahane–Zelazko characterization of characters is proved.
