Avviso seminario_Ennio Fedrizzi_Martedì 31 ottobre_ ore 11:00
by Stefano Bonaccorsi 23 Oct '17

23 Oct '17

Avviso di seminario, Università di Trento "Regularization by noise for transport and kinetic equations" Martedì 31 ottobre 2017 *Luogo:* Dipartimento di Matematica, via Sommarive, 14 - Povo (TN) - Aula Seminari "-1" *Ore*: 11.00 - *Relatore: *Ennio Fedrizzi (Applied Mathematical Department, ENSTA ParisTech) *Abstract: *For some differential equations the addition of a carefully chosen, random noise term can produce a regularising effect (e.g. solutions are more regular, or restored uniqueness). I will first mention a few easy examples (ODEs) to introduce some of these regularising mechanisms, then detail two cases where we have regularisation for a PDE: the linear transport equation and a kinetic equation with force term. I will present some classical results for these two equations, related to well-posedness and regularity of solutions, that in the stochastic setting can be obtained under weaker hypothesis. These results are based on a careful analysis of the stochastic characteristics and the regularising properties of some associated parabolic/elliptic PDE. If time allows, I will conclude by introducing a new strategy of proof based on stochastic exponentials and an associated parabolic PDE, which allows to obtain, under even weaker hypothesis, well-posedness for stochastic PDEs in a class of solutions which are only regular in mean. This will be illustrated by an application to the transport equation. *Referente: *Stefano Bonaccorsi

Seminar by prof. Walter Schachermayer at LUISS
by Sara 18 Oct '17

18 Oct '17

Dear all, on Friday 24 November at 9:30, room A105 prof Schachermayer will give the following seminar: *Title:* The amazing power of dimensional analysis: Quantifying market impact *Abstract:* A basic problem when trading in financial markets is to analyze the prize movement caused by placing an order. Clearly we expect - ceteris paribus - that placing an order will move the price to the disadvantage of the agent. This price movement is called market impact. Following Kyle and Obizhaeva we apply dimensional analysis - a line of arguments wellknown in classical physics - to analyze to which extent the square root law applies. This universal law claims that the market impact is proportional to the square root of the size of the order. The mathematical tools of this analysis reside on elementary linear algebra. Joint work with Mathias Pohl, Alexander Ristig and Ludovic Tangpi.

Fifth edition of the StaTalk series (workshops on statistical topics)
by Euloge C. Kenne Pagui 12 Oct '17

12 Oct '17

Dear all, we are pleased to announce that the fifth edition of the StaTalk series will be held at the Department of Statistical Sciences of the University of Padua, on November, 17, 2017. StaTalks are one-day workshops on statistical topics during which the hosting group introduces and overviews the main research interests of their members. Aimed at Master’s and PhD students, as well as at post-docs and young researchers, StaTalks are intended to be informal gatherings which allow for a more proficient interaction between presenters and participants. They typically feature some introductory tutorials on the main workshop theme and a few seminars that overview more advanced research topics, still kept at an expository level. StaTalks are thus a great opportunity to become acquainted with the workshop main topic, as well as to share and update one's knowledge on the interface of Statistical research in an easy and informal atmosphere. The topic of this fifth edition will cover many areas of research currently undergoing at the Department of Statistical Sciences of the University of Padua ranging from methodological statistics to demography. Registrations, as in the past StaTalk events, is free of charge but mandatory. Additional information, can be found at the workshop page statalk.stat.unipd.it Best regards, The Organising Committee --------------------------------------------------------- Department of Statistical Sciences, University of Padova.

The cost-effectiveness or business-cycle smoothing of international diversification is not always at work. How can the empirical evidence be rationalized, then? We show that diversification gains from international expansion can reduce risk margins and Solvency requirements due to longevity risk. Gains are more pronounced in a low-interest rates regime. To show that result, we build parsimonious continuous-time model for longevity risk, that captures the dependence across different ages in different populations. We define a diversification index and measure diversification gains in capital requirements according to the current regulation. We present a calibrated example, based on annuity portfolios of UK and Italian males. The results of our application show that diversification gains, evaluated as the reduction in the portfolio risk margin following the international expansion, may be non-negligible. Tai-Ho WANG (Baruch College, City University of New York) "Implied volatility and its related financial instruments: modeling and pricing" Abstract: Implied volatility modeling has been a mainstream research in academia and industry almost since the trading of options was introduced to the financial world. In this talk, we review stylized facts of implied volatility in equity market, followed by an introduction to the commonly used models that captures partly the stylized facts. The models include local volatility model, stochastic volatility model, local-stochastic volatility, and the fractional volatility model. The last in the list has been regaining great attentions these days. Numerical pricing of vanilla options and calibration of implied volatilities under these models will be briefly discussed. We conclude the talk by the pricing of financial instruments that are directly or indirectly related to implied volatilities. Dimitri Lorenzani (European Commission, Directorate General for Economic and Financial Affairs) " The European Commission's 2017 Country Report: analytical insights" Abstract: In the 2017 Country Report, the European Commission assessed Italy's economy in the light of the economic priorities established through the 2017 Annual Growth Survey: (i) boosting investment; (ii) pursuing structural reforms; and (iii) ensuring responsible fiscal policies. The presentation aims to provide insights into some of the analytical work underpinning the European Commission's findings. The Country Report indicates that, despite some important reforms in recent years, significant structural weaknesses in diverse policy areas continue to undermine Italy's productivity growth, slowing the correction of Italy's excessive macroeconomic imbalances. In particular, the high public debt remains a major source of vulnerability for the Italian economy given the low potential growth and a still fragile fiscal position. Moreover, the competitiveness gap of the Italian economy vis-à-vis the rest of the euro area persists also due to the insufficient innovation capacity of Italian firms. The legacies of the long-lasting crisis also weigh on Italy's growth prospects since sizeable non-performing loans hamper banks' ability to support investment, while long-term and youth unemployment remain high.

Seminario di Tai-Ho Wang (Department of Mathematics - Baruch College - The City University of New York) Giovedi' 19 ottobre 2017 - ore 14:30 - aula 200 Università Cattolica del Sacro Cuore, Milano, Dipartimento di Discipline matematiche, Finanza matematica ed Econometria Via Necchi, 9 - Milano TITLE: Modeling of implied volatility and its recent progress ABSTRACT: Modeling of implied volatility has been active ever since the introduction of trading of option. In this talk, starting from the minimal and complete local volatility model, we discuss the development of more sophisticated models that aim to capture stylized facts observed in the market. In addition to local volatility models, the models include stochastic volatility model, exponential Levy models, and the recently revived fractional models. We also elaborate which of the styles facts are, and which aren't, captured by these models. Numerical pricing of vanilla options and calibration of implied volatilities under these models will be briefly discussed. Tutti gli interessati sono invitati a partecipare.

=========================================================== *Subject*: 2 postdoc positions in Machine Learning (1 year, renewable up to 3 years) *Institution*: RIST - Romanian Institute of Science and Technology, Cluj-Napoca *Keywords*: Deep Learning, Reinforcement Learning, Stochastic Optimization, Optimization over Manifolds, Information Geometry, Riemannian Geometry *Application deadline*: 20 October 2017 (applicants are encouraged to apply earlier) *Salary*: around 2190 euro net *Official announcement*: http://rist.ro/en/details/news/postdoc- positions-in-deep-learning-and-machine-learning.html =========================================================== Dear colleagues, the Romanian Institute of Science and Technology (RIST) has an opening for 2 postdoc positions, in the context of the DeepRiemann project “Riemannian Optimization Methods for Deep Learning”, funded by European structural funds through the Competitiveness Operational Program (POC 2014-2020). The appointments will be for 1 year, with possible extensions up to 3 years. The DeepRiemann project aims at the design and analysis of novel training algorithms for Neural Networks in Deep Learning, by applying notions of Riemannian optimization and differential geometry. The task of the training a Neural Network is studied by employing tools from Optimization over Manifolds and Information Geometry, by casting the learning process to an optimization problem defined over a statistical manifold, i.e., a set of probability distributions. The project is highly interdisciplinary, with competences spanning from Machine Learning to Optimization, Deep Learning, Statistics, and Differential Geometry. The objectives of the project are multiple and include both theoretical and applied research, together with industrial activities oriented to transfer knowledge, from the institute to a startup or spin-off of the research group. The positions will be part of the new Machine Learning and Optimization group http://luigimalago.it/group.html, which performs research at the intersection of Machine Learning, Stochastic Optimization, Deep Learning, and Optimization over Manifolds, from the unifying perspective of Information Geometry. The group is one of two newly-formed groups in Machine Learning at RIST, where about 20 new postdoctoral research associates and research software developers will be hired by 2018. The official job announcement can be seen here: http://rist.ro/en/details/news/postdoc-positions-in- deep-learning-and-machine-learning.html Informal inquiries can be sent to Dr. Luigi Malagò <malago(a)rist.ro>, principal investigator of the DeepRiemann project. Application deadline: 20 October 2017 (applicants are encouraged to apply earlier) best regards, Luigi Malagò

seminar at LUISS
by Marco Scarsini 09 Oct '17

09 Oct '17

Thursday October 12 from 12:00 to 13:00, room 207 Department of Economics and Finance LUISS viale Romania 32 00197 Roma. Speaker: Fabio Martinelli Title: Bootstrap percolation and interacting particle systems with kinetic constraints Abstract: Recent years have seen a great deal of progress in understanding the behavior of bootstrap percolation models, a particular class of monotone cellular automata. In the two-dimensional lattice, there is now a quite satisfactory understanding of their evolution starting from a random initial condition, with a strikingly beautiful universality picture for their critical behavior (length and time scales). Much less is known for their non-monotone stochastic counterpart, namely kinetically constrained models (KCM). In KCMs the state of each vertex which could be infected by the bootstrap percolation rules is resampled (independently among the vertices) at rate one by tossing a p-coin. In particular, the infection can also heal, hence the non-monotonicity. Besides their connection with bootstrap percolation, KCMs have a strong interest in their own: as p ↓ 0 they display some of the most striking features of the liquid/glass transition, a major and still largely open problem in condensed matter physics. In this talk, after an introductory first part, I shall discuss (i) some recent conjectures relating the universality behavior of critical KCMs to their bootstrap percolation counterpart and (ii) some very recent progress towards proving the above conjectures. Joint project with C. Toninelli (Univ. Paris VII) and R. Morris (IMPA, Rio de Janeiro) ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/
