Weak Mapping Theorems,pt of the weak topology and means that these mappings are concerned with matrix elements of operators. In contrast to this are the methods which use operator products for the description of composite particles and which will be discussed in Chapter 11.

Beschreibung eindimensionaler Stichprobenrepresentations which means infinitely many different state representations. In particular, the only explicitly known state representation, the Fock representation, is a definitely wrong representation for quantum fields with mutual interaction. This fact is known as Haag’s theorem, cf. Haag [Haag 92].

Although great efforts have been made with respect to their numerical evaluation, for complicated systems, e.g. for interacting composite particles, one cannot circumvent the analytical treatment.

The Spinorfield Model,ts of elementary spin-1/2 representations, cf. Wigner [Wign 39], Fonda and Ghirardi [Fon 70], Bogoliubov, Logunov and Todorov [Bogo 75], Haag [Haag 92]. Therefore, as this group is fundamental one expects that nature reflects this composition principle, i.e. that spin-1/2 fermions are the basic quan

For quantum field theories these state spaces are assumed to be spanned by the sets of eigenstates of the commuting Poincaré generators with the corresponding eigenvalue equations (1.93). However, in contrast to quantum mechanics, these eigenvalue equations cannot be straightforwardly integra

独特性

Weak Mapping Theorems, we regard weak mapping as a suitable means for deriving effective quantum field dynamics. The attribute “weak” is borrowed from the topological concept of the weak topology and means that these mappings are concerned with matrix elements of operators. In contrast to this are the methods which use o
