The Euclidean vacuum state for linearized gravity on de Sitter spacetime

Appears in collection : 2024 - PC1 - WS - Curved spacetimes, field theory and beyond

We will explain the construction of the euclidean vacuum state for linearized gravity on de Sitter spacetime by a rigorous version of Wick rotation. We will discuss issues related to gauge invariance, positivity and invariance under de Sitter isometries.
