Stochastic Quantization of Autonomous Phi**4
U. Ritschel
The non-perturbative autonomous renormalization of the scalar -model is applied in the framework of stochastic quantization. I show that this requires a selective, momentum-de…

Autonomous Renormalization of Phi^4 in Finite Geometry
Uwe Ritschel
The autonomous renormalization of the O(N)-symmetric scalar theory is based on an infinite re-scaling of constant fields, whereas finite-momentum modes remain finite. The natural f…
