Dr. Fabricio MACIA (Univ. Complutense Madrid e Univ. di Pisa) ``Wigner measures and controllability of discrete wave equations'' Dipartimento di Matematica - Sala dei Seminari Gioved\`\i\ 28 Febbraio - ore 18.00


In this talk we shall present Wigner measures as a tool for describing the limiting energy distribution of a $L^2$-bounded sequence of discrete functions and show how they can be applied to find necessary and sufficient geometric conditions for the existence of uniformly bounded least-norm controls for discrete wave equations.
