PhD positions in Utrecht
by Tobias Mueller 11 Feb '16

11 Feb '16

VACANCY: PhD positions in Random Graphs and Percolation. Fully funded PhD positions are available at the Department of Mathematics of the University of Utrecht, to work on random graphs and percolation theory under the direction of Dr. Tobias Müller. The positions are funded by an NWO VIDI project on geometric random graphs and related percolation models. The positions are for four years and offer competitive salary and benefits. They carry a modest teaching load which, in the case of foreign applicants, can be performed in English. One position is available immediately, but starting dates are negotiable as long as they are within the next calender year. Utrecht is a lively, picturesque city in the center of the Netherlands, with excellent train connections to the rest of the country and to Europe (train trips to Amsterdam take 20 minutes and 25 minutes to Schiphol Airport). REQUIREMENTS: Candidates should have completed a Masters degree in Mathematics or a related discipline by the time they start the position. A strong background in probability theory and discrete mathematics is advantageous, but mathematical maturity and motivation are more important. APPLICATION DEADLINE: For full consideration, please apply on or before 9 March 2016. Reviewing of applications will commence on 9 March 2016, but we accept applications until all positions are filled. HOW TO APPLY: Please send the following material to t.muller(a)uu.nl: 1. A cover letter including an explanation why you consider pursuing a Ph.D. in the area of random graph theory and percolation theory; 2. An up-to-date curriculum vitae; 3. A list of all courses taken for your bachelor's and master's degrees together with grades and explanations of the grades; 4. If available, a copy of the Bachelor thesis and Master thesis; 5. The names and contact details of two academic referees, one of which should you be your master thesis supervisor. Please make sure that they also send their confidential reference letters directly to t.muller(a)uu.nl to arrive by the deadline. GENERAL INFORMATION: You will be offered a full-time position for four years. The gross monthly salary will amount to EUR 2.146,- in the first year to EUR 2.744,- in the fourth year (P-scale of the Collective Labour Agreement Dutch Universities). It is supplemented with a holiday bonus of 8% and an end-of-year bonus of 8,3% per year. In addition Utrecht University offers a pension scheme and a partially paid parental leave. INQUIRIES: If you have any questions, please send an e-mail to Tobias Müller, t.muller(a)uu.nl.

Con preghiera di diffusione tra tutti i possibili interessati, scusandomi per invii multipli. ******************************************* A v v i s o d i S e m i n a r i o ******************************************* *Martedì 9 Febbraio 2016*,*ore 15:30 precise* Aula Dottorato, Dipartimento di Matematica, Universita' degli Studi di Milano via C. Saldini 50, Milano il Professor *Paulo R. Rios*(Universidade Federal Fluminense, Volta Redonda, Rio de Janeiro, Brazil) terrà un seminario dal titolo *PROBABILISTIC COMPUTER SIMULATION OF MARTENSITE* ABSTRACT: In bulk polycrystalline materials, the first nucleation event of a martensite plate within a single grain may induce transformation in one or more neighboring grains, resulting in a cluster of partially transformed grains: 'the spread event'. The collection of these single spread events can be defined as the 'spread' or 'martensite spread'. First, in this paper, martensite spreads are analyzed to estimate the mean number of partially transformed grains in a single spread event. Secondly, taking the quantitative knowledge gained from this analysis as a starting point, a computer simulation of the martensite spread is proposed. This computer simulation is carried out in a 3-d network of space-filling grains represented as Kelvin polyhedra and is based on a probabilistic approach. The experimental and simulation results are presented, compared and discussed. We conclude that the probabilistic computer simulation of martensite spread could successfully describe important quantitative aspects of martensite spread Tutti gli interessati sono invitati a partecipare.

seminar announcement (correction)

03 Feb '16

Sorry, the previous announcement had a wrong date Tuesday, February 9, 2016 from 12:00 to 13:00 LUISS room 207 Viale Romania 32 00197 Roma Speaker Roberto Cominetti (Universidad Adolfo Ibañez) Title "Risk measures and shortest paths in network games" ABSTRACT: We consider network congestion games with risk-averse players. We review some recent proposals for computing risk-sensitive optimal paths, starting from the simplest Markowitz approach based on mean-stdev optimization. This approach presents some significant drawbacks in terms of its computational complexity, lack of monotonicity, as well as a dynamic inconsistency phenomenon which arises when one re-evaluates an optimal path along the way. This inconsistency also affects other popular measures of risk such as VaR, CVaR, and semi-deviations. As a matter of fact, under minimal conditions, we show that the only risk measures that are dynamically consistent are the so-called "entropic risk measures". With these measures, and assuming that link travel times are independent, a risk-sensitive optimal path reduces to a standard shortest path problem which can be solved efficiently. This extends directly to equilibrium situations where the network is used concurrently by many players. However, link travel time correlations are to be expected in game situations, which gives rise to a number of issues and questions that will be pointed out during the talk. This talk is based on joint work with Alfredo Torrico.

Seminario Andrea Cosso a Milano-Bicocca
by federica.masiero＠unimib.it 02 Feb '16

02 Feb '16

Il giorno 10 Febbraio, alle ore 10.30, presso il Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca, via Cozzi, 55, Edificio U5, aula 2109 (secondo piano), il Dott. Andrea Cosso, Politecnico di Milano, terrà un seminario dal titolo "Randomization method and backward SDEs for optimal control of partially observed path-dependent stochastic systems" Abstract: In the present talk we introduce a general methodology, which we refer to as the randomization method, firstly developed for classical Markovian control problem in the paper: I. Kharroubi and H. Pham "Feynman-Kac representation for Hamilton-Jacobi-Bellman IPDE", Ann. Probab., 2015. As it is well-known, the dynamic programming method is the standard methodology implemented for the study of classical Markovian control problems, which allows to relate the value function to the Hamilton-Jacobi-Bellman equation through the so-called dynamic programming principle. The key feature of the dynamic programming method is that the knowledge of the value function allows, at least in principle, to find an optimal control for the problem. This very powerful and well-known methodology breaks down (in the sense that it can not be directly implemented in a standard way) when we face control problems which present the following additional features: partial observation, path-dependence, delay in the control. On the other hand, the randomization method can be quite easily generalized and adapted to these more general control problems. The aim of the talk is to illustrate this latter point, starting with the presentation of the fundamental ideas of the randomization method. The talk is based on a joint work in progress with E. Bandini, M. Fuhrman, H. Pham. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Federica Masiero
