Conformal Null Infinity Does Not Exist for Radiating Solutions in Odd Spacetime Dimensions
Stefan Hollands, Robert M. Wald
We show that for general relativity in odd spacetime dimensions greater than 4, all components of the unphysical Weyl tensor for arbitrary smooth, compact spatial support perturbat…

Quantum Field Theory Is Not Merely Quantum Mechanics Applied to Low Energy Effective Degrees of Freedom
Stefan Hollands, Robert M. Wald
It is commonly assumed that quantum field theory arises by applying ordinary quantum mechanics to the low energy effective degrees of freedom of a more fundamental theory defined a…

Conservation of the stress tensor in perturbative interacting quantum field theory in curved spacetimes
Stefan Hollands, Robert M. Wald
We propose additional conditions (beyond those considered in our previous papers) that should be imposed on Wick products and time-ordered products of a free quantum scalar field i…
