Operad theory for singular SPDEs
In this talk, we will review some recent applications of operad theory to singular SPDEs.
It is an essential tool for characterising the chain rule symmetry in the full subcritical regime which
leads to renormalising quasilinear SPDEs with local counterterms. Also, it provides negative results
about the existence of another combinatorial set lying between multi-indices and decorated trees for
encoding expansions of solutions of singular SPDEs.
