Erickson’s Reviews > Quantum Field Theory in Curved Spacetime and Black Hole Thermodynamics > Status Update

Rereading for better understanding now that I'm a postdoc 7 years after the first time.

Okay restarted reading section 5.1. It's amazing how if you forgot all the previous chapter, it's hardly comprehensible. And it's still damn hard -.-

Section 5.1 is very unclear compared to the previous chapters :/

Damn it, this is way harder than I imagined. Almost as if you cannot penetrate these things if you are not already third year PhD working specifically for algebraic quantum field theory. Likely to be symptomatic of the entire AQFT as a field.
