Aiming to search for a signal of space-time noncommutativity, we study a quasinormal mode
spectrum of the Reissner–Nordström black hole in the presence of a deformed space-time …

Abstract We study the Sine-Gordon model with Minkowski signature in the framework of
perturbative algebraic quantum field theory. We calculate the vertex operator algebra …

We give a definition of admissible counterterms appropriate for massive quantum field
theories on the noncommutative Minkowski space, based on a suitable notion of locality. We …

We review recent results on twisted noncommutative quantum field theory by embedding it
into a general framework for the quantization of systems with a twisted symmetry. We …

We prove that a scalar quantum field theory defined on noncommutative Minkowski
spacetime with noncommuting momentum coordinates is covariant with respect to the UV/IR …

We review an approach to non-commutative geometry, where models are constructed by
quantisation of the coordinates. In particular we focus on the full DFR model and its …

Diese Dissertation ist dem Studium temperierter Distributionen mittels mikrolokaler
Methoden gewidmet. Die fundamentale Größe der mikrolokalen Analysis, die …

We study field theories on the noncommutative Minkowski space with noncommuting time.
The focus lies on dispersion relations in quantized interacting models in the Yang-Feldman …

It is shown that the n-point functions of scalar massive free fields on the noncommutative
Minkowski space are distributions which are boundary values of analytic functions. Contrary …

We show that a general variant of the Wick theorems can be used to reduce the time ordered
products in the Gell-Mann & Low formula for a certain class on non local quantum field …
