    • The $q$-Deformed Random-to-Random Family in the Hecke Algebra 

      [OWP-2025-12] Brauner, Sarah; Commins, Patricia; Grinberg, Darij; Saliola, Franco (Mathematisches Forschungsinstitut Oberwolfach, 2025-11)
      We generalize Reiner-Saliola-Welker's well-known but mysterious family of $k$-random-to-random shuffles from Markov chains on symmetric groups to Markov chains on the Type-$A$ Iwahori-Hecke algebras. We prove that the ...

    • 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, ...
