Dynamical locality of the free scalar field
Christopher J. Fewster, Rainer Verch
Dynamical locality is a condition on a locally covariant physical theory, asserting that kinematic and dynamical notions of local physics agree. This condition was introduced in [a…

Dynamical locality and covariance: What makes a physical theory the same in all spacetimes?
Christopher J. Fewster, Rainer Verch
The question of what it means for a theory to describe the same physics on all spacetimes (SPASs) is discussed. As there may be many answers to this question, we isolate a necessar…

On the notion of "the same physics in all spacetimes"
Christopher J. Fewster
Brunetti, Fredenhagen and Verch (BFV) have shown how the notion of local covariance for quantum field theories can be formulated in terms of category theory: a theory being describ…
