Diagram-free approach for convergence of tree-based models in Regularity Structures
Yvain Bruned, Usama Nadeem
In this work, we translate at the level of decorated trees some of the crucial arguments which have been used in arXiv:2112.10739 for proposing a diagram-free approach for the conv…

Convergence of space-discretised gKPZ via Regularity Structures
Yvain Bruned, Usama Nadeem
In this work, we show a convergence result for the discrete formulation of the generalised KPZ equation ,…
