Lecture notes on Malliavin calculus in regularity structures
Lucas Broux, Felix Otto, Markus Tempelmayr
Malliavin calculus provides a characterization of the centered model in regularity structures that is stable under removing the small-scale cut-off. In conjunction with a spectral…

Multi-index Based Solution Theory to the Equation in the Full Subcritical Regime
Lucas Broux, Felix Otto, Rhys Steele
We obtain (small-parameter) well-posedness for the (space-time periodic) equation in the full subcritical regime in the context of regularity structures based on multi-indic…
