Avviso di seminario, Università di Trento Parabolic theory of bi-Laplacians giovedì 8 febbraio 2018 *Luogo: *Dipartimento di Matematica, via Sommarive, 14 - Povo (TN) - Aula Seminari "-1" *Ore*: 11.00 Relatore: - Delio Mugnolo (Università di Hagen - Germania) Abstract: The integral kernel of the semigroup generated by the bi-Laplacian on $\mathbb R^d$ has been studied in several papers by E.B. Davies, while other authors have successively studied positivity issues. Most of these properties strongly depend on the fact that the bi-Laplacian acts on functions in $H^4(\mathbb R)$ as the square of the Laplacian; this is not true anymore if functions on bounded domains with generic boundary conditions are considered. We are going to show how the properties of the semigroup generated by bi-Laplacians on intervals and, more generally, network-like spaces strongly depend on the boundary conditions. Our most surprising finding is that, upon allowing the system enough time to reach diffusive regime, the parabolic equations driven by certain realizations of the bi-Laplacian on networks display Markovian features: analogous results seem to be unknown even in the classical case of domains. This is joint work with Federica Gregorio. *Referente: *Stefano Bonaccorsi

Conference "Recent Advances in Random Processes" in honor of Paolo Baldi's 70th birthday - first announcement
by Rossi Maurizia 03 Feb '18

03 Feb '18

Dear colleagues, we are glad to announce the conference "Recent Advances in Random Processes" in honor of Paolo Baldi's 70th birthday taking place in Rome on September 10-11, 2018, at Citta` dellAltra Economia, in (the picturesque) Rione Testaccio. The conference focuses on random processes and their recent use to several fields, for example finance, mathematical physics, statistics or cosmology, and wishes to celebrate Paolo Baldi's scientific contributions to probability and academic life. The meeting is supported by Gnampa-INdAM funds and the ERC Grant PASCAL n. 277742. For more details (e.g. invited speakers, registration and venue) please visit the (preliminary) conference website http://www.mat.uniroma2.it/~ricerca/probab/rarp/home.html For any other information do not hesitate to contact us at rarp(a)mat.uniroma2.it We are looking forward to welcoming you in Rome!

Prof. Macci a Pisa
by RITA GIULIANO 02 Feb '18

Il Prof. Claudio Macci sara' ospite del Dipartimento di Matematica, Universita' di Pisa, nei giorni 15, 16 e 17 febbraio prossimi. Terra' un seminario il 15 febbraio alle ore 15 in Aula Seminari. TITOLO Asymptotic behavior of some hitting probabilities for sums of IID Gaussian random sets ABSTRACT In this article, we consider sequences of partial sums of iid Gaussian random sets (with respect to the Minkowski sum) and we study the asymptotic behavior of some hitting probabilities (of suitable sets of $R^d$) for these partial sums. We also illustrate the use of the importance sampling for the estimation of these hitting probabilities by Monte Carlo simulations. We obtain the analog of well-known results for level crossing probabilities of random walks, and we refer to a version of the classical Cramér’s Theorem in large deviations for random compact sets existing in the literature. Joint work with Barbara Pacchiarotti. Tutti gli interessati sono invitati Rita Giuliano

Tutti gli interessati sono invitati a partecipare. Dipartimento di Metodi e Modelli per l'Economia, il Territorio e la Finanza Facoltà di Economia, Sapienza Università di Roma Giovedì 15 febbraio Ore 14.00, auletta A, IV piano *A new approach to spatial entropy measures* L. Altieri, D. Cocchi, G. Roli Entropy is widely employed in many applied sciences to measure the heterogeneity of observations. Recently, many attempts have been made to build entropy measures for spatial data, in order to capture the influence of space over the variable outcomes. The main limit of these developments is that all indices are computed conditional on a single distance and do not cover the whole spatial configuration of the phenomenon under study. Moreover, most of them do not satisfy the desirable additivity property between local and global spatial measures. We compare some recent developments in this field to a new approach which achieves substantial innovations. Firstly, Shannon’s entropy may be decomposed into two terms: spatial mutual information, accounting for the role of space in determining the variable outcome, and spatial global residual entropy, summarizing the remaining heterogeneity carried by the variable itself. Secondly, both terms satisfy the additivity property, being sums of partial entropies measuring what happens at different distance classes. The new entropy measures are shown to be more informative and to answer a wider set of questions than the current proposals of the literature. A case study is presented with categorical lattice data, concerning the spatial heterogeneity of land use over the Emilia Romagna region.

A tutti gli interessati. SEMINAR ANNOUNCEMENT ON BIG DATA, OPTIMIZATION AND LEARNING /Prof. Andrea Lodi //(Department of Mathematical and Industrial Engineering, Polytechnique Montréal, Canada; Canada Excellence Research Chair in Data Science for Real-Time Decision-Making) / In this talk I review a couple of applications on Big Data that I personally like and I try to explain my point of view as a Mathematical Optimizer – especially concerned with discrete (integer) decisions – on the subject. I advocate a tight integration of Machine Learning and Mathematical Optimization (among others) to deal with the challenges of decision-making in Data Science. For such an integration I try to answer three questions: 1) what can optimization do for machine learning? 2) what can machine learning do for optimization? 3) which new applications can be solved by the combination of machine learning and optimization?

Expressions of interest in the broad areas of Economics, Management and Statistics
by Giovanni Puccetti 31 Jan '18

31 Jan '18

The Department of Economics, Management and Quantitative Methods (DEMM) seeks expressions of interest for junior (post-doc and assistant professor) and senior (associate professor) positions from candidates interested in working with us in the broad areas of Economics, Management and Statistics. The University of Milan is a major research and teaching institution located in one of Europe’s most thriving cities. It is ranked in the top 200 for Economics in the Shanghai Ranking of World Universities. According to RepEc, the Department of Economics, Management, and Quantitative Methods – DEMM is one of the top five departments of economics in Italy and in the top four percent in Europe. The recent Italian research evaluation exercise (VQR 2011-2014) placed DEMM among the top 10 departments in the area of economics, management and statistics in Italy. DEMM has also been the recipient of a generous competitive funding in the recent “Bando Dipartimenti di Eccellenza” grant, awarded by the Italian ministry of education (MIUR) and aimed at creating the Centre of Excellence in Economics and Data Science (CEEDS). Particular attention will be given to candidates with an excellent research record and showing the potential to cooperate with the current members of the department in pursuing DEMM’s strategy. Informal enquiries may be directed via mail to Francesca Cottone, francesca.cottone(a)unimi.it. Interested candidates are invited to submit a CV to francesca.cottone(a)unimi.it, together with a short motivation letter specifying for which position they intend to apply for. There is no formal deadline for the expression of interest but an early assessment is expected to start in the second half of February 2018. Successful applicants will be contacted to work on the application for post-doc (2+2 years), assistant (tenure-track) or associate (permanent) professor positions. Gross salary: €30,000-40,000 according to experience (post-doc), €38,500 (assistant professor), €51,000 (associate professor) per annum. Tax exemption: a four-year tax exemption on 90 percent of the salary is available according to the Italian tax law for those candidates who have been residing outside Italy for 2 years or more. This would result in the following net salary (approx.): €33,500 (assistant professor), €45,000 (associate professor) per annum.
