Chain rule symmetry for singular SPDEs
Yvain Bruned, Vladimir Dotsenko
We characterise the chain rule symmetry for the geometric stochastic heat equations in the full subcritical regime for Gaussian and non-Gaussian noises. We show that the renormalis…

Novikov algebras and multi-indices in regularity structures
Yvain Bruned, Vladimir Dotsenko
In this work, we introduce multi-Novikov algebras, a generalisation of Novikov algebras with several binary operations indexed by a given set, and show that the multi-indices recen…
