KPZ reloaded
M Gubinelli, N Perkowski - Communications in Mathematical Physics, 2017 - Springer
We analyze the one-dimensional periodic Kardar–Parisi–Zhang equation in the language of
paracontrolled distributions, giving an alternative viewpoint on the seminal results of Hairer …

Some recent progress in singular stochastic partial differential equations
Stochastic partial differential equations are ubiquitous in mathematical modeling. Yet, many
such equations are too singular to admit classical treatment. In this article we review some …

The Dynamic Model Comes Down from Infinity
JC Mourrat, H Weber - Communications in Mathematical Physics, 2017 - Springer
We prove an a priori bound for the dynamic Φ^ 4_3 Φ 3 4 model on the torus which is
independent of the initial condition. In particular, this bound rules out the possibility of finite …

A PDE Construction of the Euclidean Quantum Field Theory
M Gubinelli, M Hofmanová - Communications in Mathematical Physics, 2021 - Springer
We present a new construction of the Euclidean Φ^ 4 Φ 4 quantum field theory on R^ 3 R 3
based on PDE arguments. More precisely, we consider an approximation of the stochastic …

Log‐Sobolev inequality for the continuum sine‐Gordon model
R Bauerschmidt, T Bodineau - Communications on Pure and …, 2021 - Wiley Online Library
We derive a multiscale generalisation of the Bakry‐Émery criterion for a measure to satisfy a
log‐Sobolev inequality. Our criterion relies on the control of an associated PDE well‐known …
