 One view is that these two approaches to QFT, the mathematically rigorous axiomatic approach and the pragmatic / empirically adequate LQFT approach, are rival research programs (see David Wallace (2006, 2011) and Doreen Fraser (2009, 2011)), though Swanson (2017) argues that they are not rival programs. Fraser (2009, 2011) argues that the interpretation of QFT should be based on the mathematically rigorous approach of axiomatic formulations of QFT. By contrast, Wallace (2006, 2011) argues that an interpretation of QFT should be based on LQFT. (Wallace, in 2006, calls his preferred QFT framework conventional QFT (CQFT), but changes his terminology to LQFT in Wallace 2011). Swanson (2017) and Egg, Lam, and Oldofedi (2017) are good overviews of the debate between Fraser and Wallace (for an extended analysis see James Fraser 2016). The debate covers many different philosophical topics in QFT, which makes it more challenging to pin down exactly what is essential to the arguments for both sides (for one view of what is essential for the debate, see Egg, Lam, and Oldofedi 2017). One issue is the role of internal consistency established by mathematical rigor versus empirical adequacy. Wallace argues that LQFT is empirically adequate since it can describe the forces of the Standard Model. LQFT has a collection of calculational techniques including perturbation theory, path integrals, and renormalization group methods. One criticism of LQFT is that the calculational techniques it uses are not mathematically rigorous. Wallace argues that renormalization group methods puts perturbative QFT, an approach within LQFT, on mathematically rigorous ground and removes the main motivation for axiomatic QFT.
