Concentration estimates for slowly time-dependent singular SPDEs on the two-dimensional torus
Nils Berglund, Rita Nader
We consider slowly time-dependent singular stochastic partial differential equations on the two-dimensional torus, driven by weak space-time white noise, and renormalised in the Wi…

Perturbation theory for the measure, revisited with Hopf algebras
Nils Berglund, Tom Klose
We give a relatively short, almost self-contained proof of the fact that the partition function of the suitably renormalised measure admits an asymptotic expansion, the coe…
