State-extension conjecture. The states on $\mathcal{W}(M, {\bf g})$ are in 1--1 correspondence with Hadamard states on $\mathcal{A}(M, {\bf g})$ with smooth truncated $n$-point fun…

Let $(M,g)$ be the spacetime under consideration and let $mathcal{O}inmathcal{K}(M,g)$. Write $mathrm{QuantLie}$ for the set … Let…

Consider the spacetime with an initial globally hyperbolic region and a future Cauchy horizon, and let a linear field theory, or an interacting field theory treated perturbatively,…
