Some recent progress in singular stochastic partial differential equations

I Corwin, H Shen - Bulletin of the American Mathematical Society, 2020 - ams.org
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 …

Paracontrolled approach to the three-dimensional stochastic nonlinear wave equation with quadratic nonlinearity

M Gubinelli, H Koch, T Oh - arXiv preprint arXiv:1811.07808, 2018 - arxiv.org
Using ideas from paracontrolled calculus, we prove local well-posedness of a renormalized
version of the three-dimensional stochastic nonlinear wave equation with quadratic …

Stochastic PDE limit of the six vertex model

I Corwin, P Ghosal, H Shen, LC Tsai - Communications in Mathematical …, 2020 - Springer
We study the stochastic six vertex model and prove that under weak asymmetry scaling (ie,
when the parameter Δ → 1^+ Δ→ 1+ so as to zoom into the ferroelectric/disordered phase …

The wave maps equation and Brownian paths

B Bringmann, J Lührmann, G Staffilani - Communications in Mathematical …, 2024 - Springer
Abstract We discuss the (1+ 1)-dimensional wave maps equation with values in a compact
Riemannian manifold. Motivated by the Gibbs measure problem, we consider Brownian …

Stochastic quantization of an Abelian gauge theory

H Shen - Communications in Mathematical Physics, 2021 - Springer
We study the Langevin dynamics of a U (1) lattice gauge theory on the two-dimensional
torus, and prove that they converge for short time in a suitable gauge to a system of …

Field-theoretic thermodynamic uncertainty relation: General formulation exemplified with the Kardar–Parisi–Zhang equation

O Niggemann, U Seifert - Journal of Statistical Physics, 2020 - Springer
We propose a field-theoretic thermodynamic uncertainty relation as an extension of the one
derived so far for a Markovian dynamics on a discrete set of states and for overdamped …

Convergence of space-discretised gKPZ via Regularity Structures

Y Bruned, U Nadeem - The Annals of Applied Probability, 2024 - projecteuclid.org
In this work, we show a convergence result for the discrete formulation of the generalised
KPZ equation∂ tu=(Δ u)+ g (u)(∇ u) 2+ k (∇ u)+ h (u)+ f (u) ξ t (x), where ξ is real-valued, Δ …

Yang–Mills measure on the two-dimensional torus as a random distribution

I Chevyrev - Communications in Mathematical Physics, 2019 - Springer
We introduce a space of distributional 1-forms Ω^ 1_ α Ω α 1 on the torus T^ 2 T 2 for which
holonomies along axis paths are well-defined and induce Hölder continuous functions on …
