The microlocal spectrum condition and Wick polynomials of free fields on curved spacetimes
R. Brunetti, K. Fredenhagen, M. Koehler
Quantum fields propagating on a curved spacetime are investigated in terms of microlocal analysis. We discuss a condition on the wave front set for the corresponding n-point distri…

New Examples for Wightman Fields on a Manifold
Martin Koehler
The product of two free scalar fields on a manifold is shown to be a well defined operator valued distribution on the GNS Hilbert space of a globally Hadamard product state. Viewed…
