Perturbative Aspects of Spectral Representations for Unitary QFTs on Space/Time NC Spaces — •Christoph Dehne — ITP, Leipzig University (Vor dem Hospitaltore 1, D – 04103 Leipzig)

We construct spectral representations for unitary quantum field theories on Space/Time noncommutative spaces and investigate the spectral measure for different Feynman rules perturbatively. Explicitly, we show how to compute nonlocal counterterms, if space does not commute with time.
