[BOOK][B] From classical field theory to perturbative quantum field theory
M Dütsch - 2019 - Springer
On the one hand, perturbative quantum field theory (pQFT) is very successful: The results
obtained by computing the lowest orders of the perturbation series are in good agreement …

Renormalization of Higher Currents of the sine-Gordon Model in pAQFT
F Zanello - Annales Henri Poincaré, 2024 - Springer
In this paper, we show that the higher currents of the sine-Gordon model are super-
renormalizable by power counting in the framework of pAQFT. First we obtain closed …

A microlocal investigation of stochastic partial differential equations for spinors with an application to the Thirring model
On ad-dimensional Riemannian, spin manifold (M, g) we consider non-linear, stochastic
partial differential equations for spinor fields, driven by a Dirac operator and coupled to an …

The extension of distributions on manifolds, a microlocal approach
NV Dang - Annales Henri Poincaré, 2016 - Springer
Let M be a smooth manifold, I ⊂ MI⊂ M a closed embedded submanifold of M and U an
open subset of M. In this paper, we find conditions using a geometric notion of scaling for t ∈ …
