References discussing renormalizability via Sobolev norms
Hawking & Hertog's paper Living With Ghosts has a nice introduction in which the authors discuss the issue of renormalizability of a field theory in terms of Sobolev norms. More specifically, they ...

Independence of $S$-matrix in QED of a gauge of EM field
Due to existence of several ways to fix a gauge of an EM field in QED, there are several ways to quantize it. That leads to non-uniqueness of photon propagator and hence to non-uniqueness of integrals ...

Renormalization in quantum field theory by discretizing space (but not time)
I'm a mathematician slowly trying to learn quantum field theory and I have a small question about renormalization, which I still have a shaky understanding of.
One common way to explain what's ...

A reference request on fundamental modular domains in the context of Gribov ambiguity
I see that there are some references in the post PE on the Gribov ambiguity.
However, resolution of this ambiguity, as stated in wiki, is to find the fundamental modular region (FMR).
I looked into ...

Point-splitting regularization for anomaly in curved spacetime
In flat spacetime, the point-splitting regularization for (chiral) anomaly is discussed in great details in Peskin and Schroeder's QFT.
Does anyone know any good references for calculating anomaly ...
