In our last lesson on Thursday, 18. May, we discussed the reconstruction theorem of M. Hairer, which can be regarded as a generalization of the  Sewing Lemma. As an application of this theorem, we recovered the theorems of T. Lyons and M. Gubinelli on rough path integration as a particular case. See Ch. 13 in Friz, Hairer.

The lecture notes (part 5) on the construction of solutions to the KPZ equation via renormalization will be available on this website, soon.
