Description

In this talk I will show how (perturbative) algebraic quantum field theory provides us with mathematical tools for studying observables in quantum gravity. These tools could be potentially applied in approaches to quantum gravity that use QFT as the basic tool (e.g. asymptotic safety program, effective QG approach). The two types of observables that I will focus on are relational observables and dressed observables. I will discuss the latter using the analogy with QED.
