Eleonora Cinti (Università di Bologna): <b><a href='/seminar/674/'>Some recent results in the study of fractional mean curvature flow</a></b><br />
Aula Seminari, Dipartimento di Matematica, Università di Pisa, 17:00<br /> </p>
<div style="font-size: smaller;"><p>We study a geometric flow driven by the fractional mean curvature. The notion of fractional mean curvature arises naturally when performing the first variation of the fractional perimeter functional. More precisely, we show the existence of surfaces which develope neckpinch singularities in any dimension $n\ge 2$. Interestingly, in dimension $n = 2$ our result gives a counterexample to Grayson Theorem for the classical mean curvature flow. We also present a very recent result, in the volume preserving case, establishing convergence to a sphere. The results have been obtained in collaboration with C. Sinestrari and E. Valdinoci.</p>

Anna L. Mazzucato: <b><a href='/seminar/676/'>On the vanishing viscosity limit for incompressible flows</a></b><br />
Sala Seminari (Dipartimento di Matematica di Pisa), 18:00<br /> </p>
<div style="font-size: smaller;"><p>I will discuss recent results on the analysis of
the vanishing viscosity limit, that is, whether solutions of the
Navier-Stokes equations converge to solutions of the Euler equations,
for incompressible fluids when walls are present. At small viscosity, a
viscous boundary layer arise near the walls where large gradients of
velocity and vorticity may form and propagate in the bulk (if the
boundary layer separates). A rigorous justification of Prandtl
approximation, in absence of analyticity or monotonicity of the data, is
available essentially only in the linear or weakly linear regime under
no-slip boundary conditions. I will present in particular a result on
concentration of vorticity at the boundary for symmetric flows and the
justification of Prandtl approximation for an Oseen-type equation
(linearization around a steady Euler flow) in general smooth domains,
quantifying the effect of curvature on the pressure correction.</p>
