DESCRIPTION:Sotirios Kotitsas\nWe examine Kraichnan’s passive scalar mod
 el on the $d$-dimensional torus. On $\\mathbb{R}^{d}$\, this model exhibit
 s anomalous dissipation and anomalous regularization. We establish that th
 e model on the torus enjoys a similar anomalous regularization property. T
 he added difficulty in this setting is the absence of translation invarian
 ce\, and to get around this\, we use a scheme relying on an expansion of t
 he correlation function of the driving noise. We establish a similar resul
 t for the Kazantsev-Kraichnan model on the torus. Based on joint work with
  Lucio Galeati and Mario Maurelli.
