An overview on the Cheeger problem
No full textThe Cheeger problem consists in minimizing the ratio "perimeter over volume" among subsets of a given, bounded domain.
This problem has connections with several variational problems (eigenvalue estimates, prescribed mean curvature, Total Variation minimization, and others).
After introducing the problem, we will focus on properties of Cheeger sets (i.e., solutions of the above minimization problem) with special emphasis on the two dimensional case. In particular, we shall present some recent results obtained in collaboration with A. Pratelli, on the characterization of Cheeger sets in non-convex, planar domains

Domain Decomposition in Optimal Control Problems for Partial Differential Equations Revisited
No full textOn boundary feedback stabilisability of a viscoelastic beam
No full textSynopsisIt is shown that a cantilevered beam with weak viscoelastic damping of Boltzmann-type can be uniformly stabilised by velocity feedback applied as a shearing force at the free end of the beam. Estimates for the viscoelastic energy are derived using the energy multiplier method. The energy decay is related to the decay of the relaxation modulus associated with the viscoelastic material.</jats:p
