Algebraic QFT in Curved Spacetime and Quasifree Hadamard States: An Introduction
Algebraic QFT in Curved Spacetime and Quasifree Hadamard States: An Introduction
Within this chapter we introduce the overall idea of the algebraic formalism of QFT on a fixed globally hyperbolic spacetime in the framework of unital $$*$$ -algebras. We point out some general features of CCR algebras, such as simplicity and the construction of symmetry-induced homomorphisms. For simplicity, we deal only …
