Paracontrolled distributions and singular PDEs

M Gubinelli, P Imkeller, N Perkowski - Forum of Mathematics, Pi, 2015 - cambridge.org
We introduce an approach to study certain singular partial differential equations (PDEs)
which is based on techniques from paradifferential calculus and on ideas from the theory of …

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 …

Geometric stochastic heat equations

Y Bruned, F Gabriel, M Hairer, L Zambotti - Journal of the American …, 2022 - ams.org
We consider a natural class of ${\mathbf {R}}^ d $-valued one-dimensional stochastic partial
differential equations (PDEs) driven by space-time white noise that is formally invariant …

Paracontrolled distributions on Bravais lattices and weak universality of the 2d parabolic Anderson model

J Martin, N Perkowski - 2019 - projecteuclid.org
We develop a discrete version of paracontrolled distributions as a tool for deriving scaling
limits of lattice systems, and we provide a formulation of paracontrolled distributions in …

Asymptotics of the eigenvalues of the Anderson Hamiltonian with white noise potential in two dimensions

K Chouk, W van Zuijlen - 2021 - projecteuclid.org
In this paper we consider the Anderson Hamiltonian with white noise potential on the box [0,
L] 2 with Dirichlet boundary conditions. We show that all of the eigenvalues divided by log L …

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 …

Elliptic stochastic quantization of Sinh-Gordon QFT

N Barashkov, FC De Vecchi - arXiv preprint arXiv:2108.12664, 2021 - arxiv.org
The (elliptic) stochastic quantization equation for the (massive) $\cosh (\beta\varphi) _2 $
model, for the charged parameter in the $ L^ 2$ regime (ie $\beta^ 2< 4\pi $), is studied. We …

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 …
