The Homogeneous Causal Action Principle on a Compact Domain in Momentum Space

Felix Finster, Michelle Frankl, Christoph Langer

The homogeneous causal action principle on a compact domain of momentum space is introduced. The connection to causal fermion systems is worked out. Existence and compactness resul…

Introduction to Causal Fermion Systems

Christoph Langer

This paper is dedicated to give a concise introduction to the theory of causal fermion systems. After putting the theory of causal fermion systems into the historical context, we r…

Existence of Minimizers for Causal Variational Principles on Compact Subsets of Momentum Space in the Homogeneous Setting

Christoph Langer

We prove the existence of minimizers in the class of negative definite measures on compact subsets of momentum space in the homogeneous setting under several side conditions (const…

Causal Variational Principles in the Infinite-Dimensional Setting: Existence of Minimizers

Christoph Langer

We provide a method for constructing (possibly non-trivial) measures on non-locally compact Polish subspaces of infinite-dimensional separable Banach spaces which, under suitable a…

Causal Variational Principles in the -Locally Compact Setting: Existence of Minimizers

Felix Finster, Christoph Langer

We prove the existence of minimizers of causal variational principles on second countable, locally compact Hausdorff spaces. Moreover, the corresponding Euler-Lagrange equations ar…
