    • Renormalisation of Singular SPDEs with Correlated Coefficients 

      [OWP-2025-09] Clozeau, Nicolas; Singh, Harprit (Mathematisches Forschungsinstitut Oberwolfach, 2025-09)
      We show local well-posedness of the g-PAM and the $\phi^{K+1}_2$-equation for $K\geq 1$ on the two-dimensional torus when the coefficient field is random and correlated to the driving noise. In the setting considered here, ...

    • Renormalised Models for Variable Coefficient Singular SPDEs 

      [OWP-2025-07] Broux, Lucas; Singh, Harprit; Steele, Rhys (Mathematisches Forschungsinstitut Oberwolfach, 2025-07)
      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 subcritical regimes. In particular, we provide ...

    • Some Notes on Pontryagin Duality of Abelian Topological Groups 

      [OWP-2025-11] Hofmann, Karl Heinrich; Kramer, Linus (Mathematisches Forschungsinstitut Oberwolfach, 2025-11)
      We consider several questions related to Pontryagin duality in the category of abelian pro-Lie groups.
