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 …

Random tensors, propagation of randomness, and nonlinear dispersive equations

Y Deng, AR Nahmod, H Yue - Inventiones mathematicae, 2022 - Springer
We introduce the theory of random tensors, which naturally extends the method of random
averaging operators in our earlier work (Deng et al. in: Invariant Gibbs measures and global …

[HTML][HTML] Stochastic quantization of Yang–Mills

I Chevyrev - Journal of Mathematical Physics, 2022 - pubs.aip.org
We review two works [Chandra et al., Publ. Math. l'IHÉS (published online, 2022) and
Chandra et al., arxiv: 2201.03487 (2022)] that study the stochastic quantization equations of …

A diagram-free approach to the stochastic estimates in regularity structures

P Linares, F Otto, M Tempelmayr, P Tsatsoulis - Inventiones mathematicae, 2024 - Springer
In this paper, we explore the version of Hairer's regularity structures based on a greedier
index set than trees, as introduced in (Otto et al. in A priori bounds for quasi-linear SPDEs in …

Stochastic quantisation of yang–mills–higgs in 3d

A Chandra, I Chevyrev, M Hairer, H Shen - Inventiones mathematicae, 2024 - Springer
We define a state space and a Markov process associated to the stochastic quantisation
equation of Yang–Mills–Higgs (YMH) theories. The state space S is a nonlinear metric …

The BPHZ theorem for regularity structures via the spectral gap inequality

M Hairer, R Steele - Archive for Rational Mechanics and Analysis, 2024 - Springer
We provide a relatively compact proof of the BPHZ theorem for regularity structures of
decorated trees in the case where the driving noise satisfies a suitable spectral gap …

Langevin dynamic for the 2D Yang–Mills measure

A Chandra, I Chevyrev, M Hairer, H Shen - … mathématiques de l'IHÉS, 2022 - Springer
We define a natural state space and Markov process associated to the stochastic Yang–Mills
heat flow in two dimensions. To accomplish this we first introduce a space of distributional …

Global existence and non-uniqueness for 3D Navier–Stokes equations with space-time white noise

M Hofmanová, R Zhu, X Zhu - Archive for Rational Mechanics and …, 2023 - Springer
We establish that global-in-time existence and non-uniqueness of probabilistically strong
solutions to the three dimensional Navier–Stokes system driven by space-time white noise …

A top-down approach to algebraic renormalization in regularity structures based on multi-indices

Y Bruned, P Linares - Archive for Rational Mechanics and Analysis, 2024 - Springer
We provide an algebraic framework to describe renormalization in regularity structures
based on multi-indices for a large class of semi-linear stochastic PDEs. This framework is …

Resonance-based schemes for dispersive equations via decorated trees

Y Bruned, K Schratz - Forum of Mathematics, Pi, 2022 - cambridge.org
We introduce a numerical framework for dispersive equations embedding their underlying
resonance structure into the discretisation. This will allow us to resolve the nonlinear …
