comment Quantum Field Theory from a mathematical point of view
If I had to guess I'd say that "vague and speculative" may be considered to be "polemical". I remember writing something along these lines two years ago at the nCafe :-) (golem.ph.utexas.edu/category/2009/10/…)

comment Extensions of DHR superselection theory to long range forces
Thanks for the tip! I am curious about Bucholz's conlcusion "Origin of infrared difficulties can be traced back to unreasonable idealization of observations covering all of Minkowski space". I remember asking about this idealization in all QFT calculations in an introductory class, but had no idea that this would reappier in such a context :-)

Well, that's a good start :-) But I'll leave the question open for now.

comment Status of local gauge invariance in axiomatic quantum field theory
@Urs, thanks, so a better question to ask would be how to classify nets coming from certain quantization procedures of gauge theories, or maybe to classify gauge theories which produce Haag-Kastler nets. BTW, I think it is also possible to chat in certain chat rooms here, which would be - maybe - easier for a longer conversation like the one that happened here.

comment Status of local gauge invariance in axiomatic quantum field theory
Well, maybe, but how? But please note that the question is not "do we need local gauge symmetry" but "do we need local gauge symmetry in the framework of AQFT", with the latter being somewhat more precise than the former.

comment Status of local gauge invariance in axiomatic quantum field theory
Ok, maybe I should explain my own viewpoint of what AQFT is: That it should be able to describe the same phenomena as the standard model.
