SUMMARY:Free boundary limit and rate of convergence for tumour growth mode
 ls with a drift - Noemi David (Sorbonne Université\, Università di Bolog

DESCRIPTION:Porous medium models are widely used in the literature to desc
 ribe the mechanical properties of living tissues\, both using PDE (compres
 sible) models and geometric problems. These two classes can be related usi
 ng a stiff pressure law. In the incompressible (or stiff) limit\, the comp
 ressible model generates a free boundary problem of Hele-Shaw type. In thi
 s talk\, I will present the stiff limit of a model including convective ef
 fects\, and show that the convergence rate can be computed in a negative S
 obolev norm.\n
