An analytic BPHZ theorem for regularity structures

A Chandra, M Hairer�- arXiv preprint arXiv:1612.08138, 2016 - arxiv.org
We prove a general theorem on the stochastic convergence of appropriately renormalized
models arising from nonlinear stochastic PDEs. The theory of regularity structures gives a …

Renormalising SPDEs in regularity structures

Y Bruned, A Chandra, I Chevyrev…�- Journal of the European�…, 2020 - ems.press
The formalism recently introduced in [BHZ19] allows one to assign a regularity structure, as
well as a corresponding “renormalisation group”, to any subcritical system of semilinear …

The dynamical sine-Gordon model in the full subcritical regime

A Chandra, M Hairer, H Shen�- arXiv preprint arXiv:1808.02594, 2018 - arxiv.org
We prove that the dynamical sine-Gordon equation on the two dimensional torus introduced
in [HS16] is locally well-posed for the entire subcritical regime. At first glance this equation is …

Langevin dynamic for the 2D Yang–Mills measure

A Chandra, I Chevyrev, M Hairer, H Shen�- …�math�matiques de l'IH�S, 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 …

A priori bounds for 2-d generalised Parabolic Anderson Model

A Chandra, GL Feltes, H Weber�- arXiv preprint arXiv:2402.05544, 2024 - arxiv.org
We show a priori bounds for solutions to $(\partial_t - \Delta) u = \sigma (u) \xi$ in finite volume
in the framework of Hairer's Regularity Structures [Invent Math 198:269--504, 2014]. We …
