PhD positions at the Institute of Science and Technology Austria (IST Austria)
by Giovanni Zanco 24 Nov '16

24 Nov '16

Dear Colleague, The *Institute of Science and Technology Austria (IST Austria)* is looking for highly qualified candidates to apply for our ISTScholar PhD program. We offer *fully-funded PhD positions* in the natural and mathematical sciences in a world-class research environment on the outskirts of Vienna. The research topics that might interest students in your department include: *Mathematics* - Nick Barton: Mathematical Models of Evolution - Herbert Edelsbrunner: Algorithms, Computational Geometry and Topology - Lászlá Erdős: Mathematical Physics, Probability - Julian Fischer: Theory of Partial Differential Equations, Applied and Numerical Analysis - Tamas Hausel: Geometry and its Interfaces - Jan Maas: Stochastic Analysis, Optimal Transport - Robert Seiringer: Quantum Statistical Mechanics, Mathematical Physics - Uli Wagner: Discrete and Computational Geometry and Topology Our PhD program is characterized by innovative training with a special focus on interdisciplinarity, close mentoring by outstanding faculty within small research groups, and access to first-rate facilities. Students spend the first year completing coursework and rotations before choosing a thesis group and passing the qualifying exam. Our PhD graduates have gone on to top positions in academia and industry all over the world. Students with a *bachelor’s* *or* *master’s* degree in a relevant field are encouraged to apply. We offer *internationally competitive salaries* co-funded by an EU Marie Sklodowska-Curie grant, full health benefits, and subsidized on-campus housing in the first year. For more information about the ISTScholar PhD program and application process, as well as faculty profiles, please visit our website at http://phd.ist.ac.at. *The deadline for PhD applications is January 8th 2017 for a start date in September 2017*.

*Dipartimento di Matematica, Sapienza Università di Roma * *Martedì 29 novembre* * Ore 14:00, Aula di Consiglio* * Seminario di Probabilità e Statistica Matematica* *Pietro Caputo, Dipartimento di Matematica, Università di Roma Tre* *Titolo: Random walk on sparse random directed graphs* *Abstract: **A random walk on a finite graph exhibits cutoff if its distance from stationarity remains close to the initial value for a certain number of iterations and then abruptly drops to near zero on a much shorter time scale. Originally discovered in the context of card shuffling by Aldous and Diaconis in 1986, this remarkable phenomenon is now rigorously established for many reversible chains. Here we consider the non-reversible case of random walks on sparse random directed graphs, for which even the stationary distribution is far from being understood. We establish the cutoff phenomenon, determine its time window and prove that the cutoff profile approaches a universal gaussian shape. Moreover, we determine an explicit recursive equation characterizing the stationary distribution. This talk is based on joint work with Charles Bordenave and Justin Salez.* *Tutti gli interessati sono invitati a partecipare.* *Per qualsiasi richiesta di informazioni rivolgersi a **piccioni(a)mat.uniroma1.it <piccioni(a)mat.uniroma1.it>.*

Seminario di Tiziano De Angelis presso la Luiss, Mercoledi' 23 Novembre ore 18 e 10
by Fausto Gozzi 23 Nov '16

23 Nov '16

Luiss, Roma, Dipartimento di Economia e Finanza Viale Romania 32, Roma Mercoledi' 23 Novembre ore 18.10 aula 106 b Seminario di Tiziano De Angelis (University of Leeds) TITLE: The dividend problem with a finite horizon ABSTRACT: We characterize the value function of the optimal dividend problem with a finite time horizon as the unique classical solution of a suitable Hamilton-Jacobi-Bellman equation. The optimal dividend strategy is realized by a Skorokhod reflection of the fund's value at a time-dependent optimal boundary. Our results are obtained by establishing for the first time a new connection between singular control problems with an absorbing boundary and optimal stopping problems on a diffusion reflected at an elastic boundary.
