# Causal Fermion Systems: Discrete Space-Times, Causation and Finite Propagation Speed

@article{Finster2018CausalFS, title={Causal Fermion Systems: Discrete Space-Times, Causation and Finite Propagation Speed}, author={Felix Finster}, journal={Journal of Physics: Conference Series}, year={2018}, volume={1275} }

The theory of causal fermion systems is a recent approach to fundamental physics. Giving quantum mechanics, general relativity and quantum field theory as limiting cases, it is a candidate for a unified physical theory. The dynamics is described by a novel variational principle, the so-called causal action principle. The causal action principle does not rely on a presupposed space-time structure. Instead, it is a variational principle for space-time itself as well as for all structures in space…
