Talks

The following is the list of speakers in alphabetic order. Click the title to read the abstract.

Speaker	Affiliation	Title of the talk
Claudia Ceci	Sapienza Università di Roma	Filtering and applications to Economics, Finance, and Insurance The aim of the talk is to give an overview of filtering theory and applications. Filtering is concerned with the following problem. Suppose that we are given some signal process X describing a phenomenon which is not directly observable. Instead we can observe another stochastic process Y which is a function of the signal perturbed by some random noise. Solving a filtering problem means to characterise the filter, that is the conditional distribution of the unobservable signal process X given the information flow generated by the observable process Y. Except for a few special cases, the filter is an infinite-dimensional process, and in many situations, it can be characterized as the unique solution of a stochastic differential equation (the so called Kushner-Stratonovich equation). In this talk we also discuss applications of stochastic models under partial information in Economics, Finance and Insurance.
Barbara Fantechi	Scuola Internazionale Superiore di Studi Avanzati	Enumerative geometry after string theory Enumerative geometry asks how many solutions a geometric question has: as example, given four generic lines in 3 space, there are exactly two other lines meeting all four. At the beginning of the 90s, new ideas from physics led to striking formulas for classical questions, if they could be put on a mathematically solid basis. This led to a Fields medal for a physicist (Edward Witten), and set the ball rolling for a veritable avalanche of new ideas and results that shows no sign of slowing down, three decades later.
Benedetta Morini	Università degli Studi di Firenze	Adaptive optimization methods based on random models The interest in unconstrained optimization methods using random estimates of function values and derivatives is large and motivated by many applications including machine learning. A large and widely employed class of stochastic gradient type algorithms requires a computationally expensive parameter tuning for each application and has stimulated research on adjusting models and parameters dynamically along the iterations. Adaptive optimization methods make a dynamic choice of both the step-size and the accuracy of function estimates and models. Remarkably, random estimates are required to be sufficiently accurate with sufficiently high probability but can be arbitrarily inaccurate otherwise. The aim of this talk is to give an overview of optimization methods based on random models putting emphasis on their application to problems arising in machine learning, and to discuss open areas of research.
Michela Procesi	Università degli Studi di Roma Tre	Stability and recursive solutions in Hamiltonian PDEs In the context of Hamiltonian Partial Differential Equations on compact manifolds (mainly tori), I shall discuss the existence of special recursive solutions, close to an elliptic fixed point, whichare superposition of oscillating motions, together with their stability/instability properties. One can envision such equations as chains of harmonic oscillators coupled by a small non-linearity, thus one expects a complicated interplay between chaotic and recursive phenomena due to resonances and small divisors.
Corinna Ulcigrai	Universität Zürich	Billiards, butterflies and doughnuts: exploring slow chaos Mathematical billiards provide an idealization of the game of billiard, which model many physical systems and offer a playground for mathematicians to study chaos. A well popularized feature of chaotic systems is the butterfly effect. We will focus in this talk on polygonal mathematical billiards and more in general systems which display a 'slow form' of butterfly effect. We will mention some of the recent developments in the study of billiards in polygons and more generally slow chaos, as well as the work of several women mathematicians behind them.
