A Stochastic Flow for the Stochastic Allen-Cahn Equation with Multiplicative Noise
Salvador Esquivel, Hendrik Weber
We establish the existence of a stochastic flow on for the stochastic Allen-Cahn equation with multiplicative noise \[ (\partial_t - \partial_x^2) u = u -…
A priori bounds for 2-d generalised Parabolic Anderson Model
Ajay Chandra, Guilherme de Lima Feltes, Hendrik Weber
We show a priori bounds for solutions to in finite volume in the framework of Hairer's Regularity Structures [Invent Math 198:269--504, 2014]. We a…
A priori bounds for stochastic porous media equations via regularity structures
Markus Tempelmayr, Hendrik Weber
We prove a priori bounds for solutions of singular stochastic porous media equations with multiplicative noise in their natural -based regularity class. We consider the first…
Stochastic quantization of - theory in 2-d Moyal space
Chunqiu Song, Hendrik Weber, Raimar Wulkenhaar
There is strong evidence for the conjecture that the QFT- model on 4-dimensional non-commutative Moyal space can be non-perturbatively constructed. As preparation, in this…
Scaling limit of a weakly asymmetric simple exclusion process in the framework of regularity structures
Ruojun Huang, Konstantin Matetski, Hendrik Weber
We prove that a parabolically rescaled and suitably renormalised height function of a weakly asymmetric simple exclusion process on a circle converges to the Cole-Hopf solution of…
Holley--Stroock uniqueness method for the dynamics
Roland Bauerschmidt, Benoit Dagallier, Hendrik Weber
The approach initiated by Holley--Stroock establishes the uniqueness of invariant measures of Glauber dynamics of lattice spin systems from a uniform log-Sobolev inequality. We use…
