On the local structure of the Klein-Gordon field on curved spacetimes
Alexander Strohmaier
This paper investigates wave-equations on spacetimes with a metric which is locally analytic in the time. We use recent results in the theory of the non-characteristic Cauchy probl…

The Reeh-Schlieder Property for the Dirac Field on Static Spacetimes
Alexander Strohmaier
We prove the Reeh-Schlieder property for the ground- and KMS-states states of the massive Dirac Quantum field on a static globally hyperbolic 4 dimensional spacetime.

Towards a Nonperturbative Covariant Regularization in 4D Quantum Field Theory
H. Grosse, A. Strohmaier
We give a noncommutative version of the complex projective space CP^2 and show that scalar QFT on this space is free of UV divergencies. The tools necessary to investigate Quantum…
