An equivalence theorem for algebraic and functorial QFT
Severin Bunk, James MacManus, Alexander Schenkel
The paper introduces a flexible notion of Lorentzian bordisms to define functorial quantum field theories and proves an equivalence between these theories and algebraic quantum fie…

Lorentzian bordisms in algebraic quantum field theory
Severin Bunk, James MacManus, Alexander Schenkel
It is shown that every algebraic quantum field theory has an underlying functorial field theory which is defined on a suitable globally hyperbolic Lorentzian bordism pseudo-categor…
