Boundary behaviour of Robin problems and isoperimetric spectral inequalities

Speaker: Dorin Bucur (Université de Savoie).

The Lisbon Webinar in Analysis in Differential Equations is a joint iniciative of CAMGSD, CMAFcIO and GFM, three research centers of the University of Lisbon. It is aimed at filling the absence of face-to-face seminars and wishes to be a meeting point of mathematicians working in the field.

On the uniform distribution of dislocations

Speaker: Riccardo Scala (Università degli Studi di Siena).

Abstract: We discuss a model for dislocations at a semi-coherent interface between two crystals. We investigate and prove some results on the optimal distribution of dislocations. Finally we relate our models to others and present some open problems (collaboration with M. Ponsiglione and S. Fanzon).

Initial-boundary value problems for generalized Kelvin-Voigt equations

Por Khompysh Khonatbek (al-Farabi Kazakh national university).

Abstract: In this talk the initial-boundary value problems for modified Kelvin-Voigt equations with p,q-Laplace will be considered. The unique solvability and the quality properties as blow-up in a finite time and large time behaviour of the weak solution will be proved.
