MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV ( that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

The Principle of the Fermionic Projector III, Normalization of the Fermionic States

Felix Finster


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.
