Antonia Diana: Length–penalized elastic flow of curves with partial free boundary

Abstract: Geometric gradient flows for elastic energies play an important role in mathematics and in many applications.
In this talk we consider a curve with boundary points free to move on a line in R^2, which evolves by the L^2-gradient flow of the elastic energy, that is a linear combination of the Willmore and the length functional.
For such planar evolution problem we study the short and long–time existence.
Once we establish the well-posedness in the case of Navier boundary conditions, employing the Solonnikov theory for linear parabolic systems in Hölder space, we show that there exists a unique flow in a maximal time interval [0,T) and it is unique in a purely geometric sense. Finally, using energy methods we prove that maximal time is actually T=+∞.

 

Domenico Vuono: Second and third order estimates for solutions to $p$-Laplace equations.

Abstract: We consider solutions to

            $$ – Delta_{p} u = f(x) quad text{in } Omega, ,$$

when $p$ approaches the semilinear limiting case $p=2$ and we get third order estimates. As a consequence we deduce improved regularity properties of the stress field. The results presented in this seminar are contained in a recent paper with D. Baratta and B. Sciunzi. Finally, I present a $L^infty$-estimate for the second derivative of the solution. This is a recent result in preparation with F. Iandoli.
