An analytic BPHZ theorem for regularity structures
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
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
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
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
We show a priori bounds for solutions to $(\partial_t - \Delta) u = \sigma (u) \xi$ in finite volume
