On the Initial Value Problem for Causal Variational Principles
Felix Finster, Andreas Grotz
We formulate the initial value problem for causal variational principles in the continuous setting on a compact metric space. The existence and uniqueness of solutions is analyzed.…

Causal Fermion Systems: A Quantum Space-Time Emerging from an Action Principle
Felix Finster, Andreas Grotz, Daniela Schiefeneder
Causal fermion systems are introduced as a general mathematical framework for formulating relativistic quantum theory. By specializing, we recover earlier notions like fermion syst…

The Causal Perturbation Expansion Revisited: Rescaling the Interacting Dirac Sea
Felix Finster, Andreas Grotz
The causal perturbation expansion defines the Dirac sea in the presence of a time-dependent external field. It yields an operator whose image generalizes the vacuum solutions of ne…
