Lorentzian Spectral Geometry for Globally Hyperbolic Surfaces
Felix Finster, Olaf Müller
The fermionic signature operator is analyzed on globally hyperbolic Lorentzian surfaces. The connection between the spectrum of the fermionic signature operator and geometric prope…
The Continuum Limit of a Fermion System Involving Leptons and Quarks: Strong, Electroweak and Gravitational Interactions
Felix Finster
The causal action principle is analyzed for a system of relativistic fermions composed of massive Dirac particles and neutrinos. In the continuum limit, we obtain an effective inte…
The Chiral Index of the Fermionic Signature Operator
Felix Finster
We define an index of the fermionic signature operator on even-dimensional globally hyperbolic spin manifolds of finite lifetime. The invariance of the index under homotopies is st…
Spinors on Singular Spaces and the Topology of Causal Fermion Systems
Felix Finster, Niky Kamran
Causal fermion systems and Riemannian fermion systems are proposed as a framework for describing non-smooth geometries. In particular, this framework provides a setting for spinors…
Perturbative Description of the Fermionic Projector: Normalization, Causality and Furry's Theorem
Felix Finster, Jürgen Tolksdorf
The causal perturbation expansion of the fermionic projector is performed with a contour integral method. Different normalization conditions are analyzed. It is shown that the corr…
