Seminarium KMMF "Teoria Dwoistości"

In this talk, I will present some motivations and technical difficulties that appear when one tries to do Quantum Field Theory in spacetimes with limited regularity. I will focus particularly on the causal propagator and the two-point function of the quasi-free states and its relationship with adiabatic states. Because this is a work in progress only preliminary results and general strategies will be discussed.
