Renormalised Models for Variable Coefficient Singular SPDEs
Lucas Broux, Harprit Singh, Rhys Steele
In this work we prove convergence of renormalised models in the framework of regularity structures [Hai14] for a wide class of variable coefficient singular SPDEs in their full sub…

Renormalisation of Singular SPDEs with Correlated Coefficients
Nicolas Clozeau, Harprit Singh
We show local well-posedness of the g-PAM and the -equation for on the two-dimensional torus when the coefficient field is random and correlated to the driving…

Canonical solutions to non-translation invariant singular SPDEs
Harprit Singh
We exhibit a canonical, finite dimensional solution family to certain singular SPDEs of the form \begin{equation} \left(\partial_t- \sum_{i,j=1}^d a_{i,j}(x,t) \partial_i \partial_…
