For an introduction to the subject you may want to have a look at the
Introductory article Causal fermion systems as a candidate for a unified physical theory, J. Phys.: Conf. Ser. 626 (2015) 012020
as well as at the
Book The Continuum Limit of Causal Fermion Systems (PDF).
The school will also cover the necessary mathematical and physical background, adapted to the knowledge of the participants, as explained in a book which we are currently writing:
Book "An Introduction to the Fermionic Projector and Causal Fermion Systems," in preparation.
More detailed references will be given during the school.
