Construction of Hadamard states for Klein‐Gordon fields
Apparaît dans la collection : Summer School 2014 - Asymptotic Analysis in General Relativity
We will review a new construction of Hadamard states for quantized Klein-Gordon fields on curved spacetimes, relying on pseudo differential calculus on a Cauchy surface. We also present some work in progress where Hadamard states are constructed from traces of Klein-Gordon fields on a characteristic cone. (Joint work with Michal Wrochna).
