The Principle of the Fermionic Projector III, Normalization of the Fermionic States
The normalization of the states of the fermionic projector is analyzed. By considering the system in finite 4-volume and taking the infinite volume limit, it is made precise what "idempotence" of the fermionic projector means. It is shown that for each fermionic state, the probability integral has a well-defined infinite volume limit.
