SUMMARY:Massimo Sorella (Lausanne): Enhanced dissipation for non-degenerate
  elliptic points
DESCRIPTION:Title\nEnhanced dissipation for non-degenerate elliptic points\
 nAbstract\n\nWe study dissipation enhancing properties of the advection-di
 ffusion equation advected by a class of Hamiltonian flows with a non-degen
 erate elliptic point which are quantitatively close to radial flows. Namel
 y\, we aim at establishing a convergence towards the streamline average on
  sub-diffusive timescales. The precise timescale is given as a function of
  the asymptotic behaviour of the period function. In particular\, we recov
 er the enhanced dissipation rates for radial flows. Our proof is based on 
 spectral techniques applied to a model problem (for which we can consider 
 more general Hamiltonian flows such as the cellular flow). This is a joint
  work with M. Dolce and C. Johansson.\n\nPlease note that the seminar will
  take place in person in room 140 of Huxley Building.\n\nClick here to get
