### Seminari Passati

• Financial stability and macroprudential policy
Stefano Borgioli, European Central Bank
martedì 7 maggio 2019 alle ore 17:00, Aula seminari del sesto piano
ABSTRACT
Financial stability can be defined as a condition in which the financial system – which comprises financial intermediaries, markets and market infrastructures – is capable of withstanding shocks and the unravelling of financial imbalances. In the seminar we discuss some financial stability analysis tools and the implications on macroprudential policy at ECB.

• Markovian Extensions of Symmetric Second Order Elliptic Differential Operators
Andrea Posilicano, Università degli Studi dell'Insubria
martedì 30 aprile 2019 alle ore 15:15, Aula seminari 3° piano
ABSTRACT
We give a complete classification of the Markovian self-adjoint extensions of the minimal realization of a second order elliptic differential operator on a bounded n-dimensional domain by providing an explicit one-to-one correspondence between such extensions and the class of Dirichlet forms on the boundary which are additively decomposable by the bilinear form of the Dirichlet-to-Neumann operator plus a Markovian form. By such a result two further equivalent classifications are provided: the first one is expressed in terms of a decomposition of the bilinear forms associated to the extensions, the second one uses the decomposition of the resolvents provided by the Krein formula. The Markovian part of the decomposition allows to characterize the operator domain of the corresponding extension in terms of Wentzell-type boundary conditions. Some analogous results hold also in a nonlinear setting.
• Limit Theorems for the Fractional Non-homogeneous Poisson Process
Enrico Scalas, University of Sussex
martedì 16 aprile 2019 alle ore 14:30, Aula seminari del sesto piano
ABSTRACT
The fractional non-homogeneous Poisson process was introduced by a time-change of the non-homogeneous Poisson process with the inverse ?-stable subordinator. We propose a similar definition for the (non-homogeneous) fractional compound Poisson process. We give both finite-dimensional and functional limit theorems for the fractional non-homogeneous Poisson process and the fractional compound Poisson process. The results are derived by using martingale methods, regular variation properties and Anscombe's theorem. Eventually, some of the limit results are verified in a Monte Carlo simulation.

This is a joint work with Nikolai Leonenko and Mailan Trinh.
• MATLAB Tools for Large-Scale Linear Inverse Problems
James Nagy, Emory University
lunedì 15 aprile 2019 alle ore 14:30, Aula Seminari 'Saleri' VI Piano MOX-Dipartimento di Matematica, Politecnico di Milano - Edificio 14
ABSTRACT
Inverse Problems Inverse problems arise in a variety of applications: image processing, finance, mathematical biology, and more. Mathematical models for these applications may involve integral equations, partial differential equations, and dynamical systems, and solution schemes are formulated by applying algorithms that incorporate regularization techniques and/or statistical approaches. In most cases these solutions schemes involve the need to solve a large-scale ill-conditioned linear system that is corrupted by noise and other errors. In this talk we describe and demonstrate capabilities of a new MATLAB software package that consists of state-of-the-art iterative methods for solving such
systems, which includes approaches that can automatically estimate regularization parameters, stopping iterations, etc., making them very simple to use. Thus, the package allows users to easily incorporate into their own applications (or simply experiment with) different iterative methods and regularization strategies with very little programming effort. On the other hand, sophisticated users can also easily access various options to tune the algorithms for certain applications. Moreover, the package includes several test problems and examples to illustrate how the iterative methods can be used on a variety of large-scale inverse problems.
The talk will begin with a brief introduction to inverse problems, discuss considerations that are needed to compute an approximate solution, and describe some details about new efficient hybrid Krylov subspace methods that are implemented in our package. These methods can guide users in automatically choosing regularization parameters, and can be used to enforce various regularization schemes, such as sparsity. We will use imaging examples that arise in medicine and astronomy to illustrate the performance of the methods. This is joint work with Silvia Gazzola (University of Bath) and Per Christian Hansen (Technical University of Denmark).

martedì 9 aprile 2019 alle ore 11:30, Aula Seminari 'Saleri' VI Piano MOX-Dipartimento di Matematica, Politecnico di Milano - Edificio 14
ABSTRACT
The progress of powerful experimental techniques such as Cryo--?Electron
Microscopy represents a remarkable opportunity but also a significant challenge for computational techniques, which aim at extracting useful information and predicting the behavior of bio molecular systems. While pioneering attempts to perform molecular dynamics
Simulation at this scale by means of super--?computers have been made, there still is the compelling need for enabling tools and approaches able to routinely analyze this kind
of structures, identifying, for instance, interaction hot spots or new target regions for next generation drug discovery ....
