We propose a two-phase gradient-based method for general Quadratic Programming (QP) problems. Such kind of problems arise in many real-world applications, such as Support Vector Machines, multicommodi...
I sistemi di equazioni alle derivate parziali di tipo iperbolico danno luogo a soluzioni con una struttura particolarmente interessante. Dati iniziali e al contorno regolari possono sviluppare singola...
Abstract: In 1978 Wannier discovered a Diophantine relation expressing the integrated density of states of a gapped group of bands of the Hofstadter Hamiltonian as a linear function of the magnetic fi...
Il principio della Programmazione Dinamica per problemi di controllo ottimo si basa sulla caratterizzazione della funzione valore come l'unica soluzione di viscosità dell'equazione di Hamilton-Jacobi-...
We consider an arbitrary family of stochastically ordered distribution functions dependent on parameters from an interval in the real line. We compare distribution functions and moments of random vari...
Let us consider a functional equation Ax=y characterized by an ill-posed linear operator A acting between two Banach spaces X and Y. In this talk, we propose an extension of the Tikhonov regularizatio...
We consider lattice approximations of the Allen-Cahn equation on the torus perturbed by small space-time white noise and discuss metastable transition times between the two stable phases....
Abstract: We consider a system of non-relativistic bosons interacting through a regular, positive potential vv with scattering length aa. We give a simple proof that the ground state energy density sa...
In this course we will review recent work on the different upper bounds for the ground state energy of a gas of interacting bosons in the thermodynamic limit. We start by considering quasi-free states...
Si discutono alcuni risultati che riguardano comportamenti effettivi di sistemi quantistici a bassa energia, caratterizzati da un singolo parametro fisico noto come lunghezza di scattering. Si fara' i...
