DESCRIPTION:Speaker: Fabio Toninelli\nhosted by M. Beiglböck\, N. Berestyc
 ki\, L. Erdös\, J. Maas\, F. Toninelli\nAbstract: The AKPZ equation is an
  anisotropic variant of the celebrated (two-dimensional) KPZ stochastic PD
 E\, which is expected to describe the large-scale behavior of (2+1)-dimens
 ional  growth models whose average speed of growth is a non-convex functi
 on of the average slope (AKPZ universality class). Several interacting par
 ticle systems belonging to the AKPZ class are known\, notably a class of t
 wo-dimensional interlaced particle systems introduced by A. Borodin and P.
  Ferrari. The AKPZ equation has been conjectured to have the same  large-
 scale behavior as the stochastic heat equation with additive noise (2d-SHE
 ). In this talk\, I will show that this is not really true: in fact\, the 
 stationary equation is not invariant under diffusive rescaling (as the 2d-
 SHE is)\, not even asymptotically on large scales\, as the diffusion coeff
 icient diverges (logarithmically) for large times. [Based on joint work wi
 th G. Cannizzaro and D. Erhard]
