A minimization approach to the wave equation on time-dependent domains.

Relatore: 
Lucia De Luca
Abstract. We prove the existence of weak solutions to the homogeneous wave equation on a suitable class of time-dependent domains. Using the approach suggested by De Giorgi and developed by Serra and Tilli, such solutions are approximated by minimizers of suitable functionals in space-time. Joint work with Gianni Dal Maso.

Cryptography, Quantum Computation and Selberg's Sieve

 

We will discuss Shor's algorithm for factorization of integers using quantum computers. This algorithm employs Miller's algorithm, which we will also discuss. We will then explore an alternative, non-quantum, attempt to exploit Miller's algorithm. To do this we will introduce a new sort of discrete dynamical system, based on number theory. We will go on to begin analyzing this dynamical system using the theory of sieves.

Transversally strictly hyperbolic systems

Relatore: 
Prof. Tatsuo Nishitani

Abstract:
We consider the Cauchy problem for first-order systems. Assuming that the  set of singular points of characteristic variety is a smooth manifold and the characteristic values are real and semisimple we introduce a new class which is strictly hyperbolic in the directions transverse to this manifold.  In this talk I mainly discuss  an interesting example proposed by G.Me'tivier which is transversally strictly hyperbolic but the propagation cone is incompatible with the set of singular points of characteristic variety.

Analysis of Novel Domain Wall Types in Ferromagnetic Nanostructures

Abstract. Recent advances in nanofabrication allow an unprecedented degree of control of ferromagnetic materials down to the atomic scale, resulting in novel nanostructures whose properties are often dominated by material interfaces. Mathematically, these systems give rise to challenging problems in the calculus of variations that feature non-convex, vectorial, topologically constrained, multi-scale variational problems.
