Prologue: The Algebraic Approach to Quantum Theories,This chapter should be considered as a prologue to the book. It gives a brief and informal introduction to the algebraic approach to quantum theories and provides some physical motivation for the study of general .-representations and states of .-algebras.

Die kurative ambulante Behandlung,his chapter. The ordering, the orthogonality, and the transition probability of positive linear functionals are investigated in detail. A Radon–Nikodym theorem is proved and the Choquet theory is used to obtain extremal decompositions of states. Finally, quadratic modules are defined by means of .-representations.
