How are point-dependent concepts such as correlation functions, renormalization, cluster decomposition...etc interpreted in axiomatic QFT?
In traditional quantum field theory we often speak about things happening at a point. For example, the correlation function
$$\langle 0 | \phi(x) \phi(y)\ | 0\rangle \tag{1}$$
can be thought of the ...
