The First DinAmicI Day to be held at Gran Sasso Science Institute in L’Aquila is approaching. For people arriving on the 24th, we are meeting at the restaurant “Il primo papavero” for dinner.

This is the program of the event (25 November 2016):

9:00-9:50   Mauro Artigiani, “Lagrange spectrum of Veech translation surfaces” 10:00-10:50  Anna Miriam Benini, “Singular values and periodic points” 11:00-11:30  Coffee Break 11:30-12:20  Sara Munday, “Slippery Devil’s Staircases”

12:45-14:30  Lunch Break

The Department of Mathematics of Università di Bologna has opened a call for two 1-year postdoctoral positions denominated “Starting postdoctoral position in Mathematics and Applications in Sciences, Social Sciences and Engineering”.

The positions are open to all candidates who hold a Ph.D. in Mathematics, Physics, Computer Science, Engineering, Statistics or Economics, with a preference for applicants who have obtained their Ph.D.’s in recent years.  It is an “open” position in that all research areas that are currently represented in the Department will be considered (see the announcement for a list of them). The candidate is invited to contact a faculty member to evaluate the feasibility of his/her research proposal.

Applications are invited for a 3 year Research Associate role in Mathematics, tenable from 1 October 2017 (or a nearby date to be agreed). The aim of this project, funded by EPSRC UK, is to perform cutting edge research in the following two fields of modern probability theory and stochastic processes: (a) random walks and diffusions with long memory (including self-interacting walks, walks in random environment, tracer diffusion in interacting particle systems); (b) stochastic representations in statistical mechanics with special emphasis on quantum spin and particle systems. The Research Associate will work with Professor Balint Toth at the School of Mathematics, University of Bristol.

“A geometric model for the natural extension of continued fraction maps”

Abstract: Just as classical “Floor” continued fractions induce the Gauss map on the real unit interval, other euclidean division algorithms (Ceiling, Even, Odd, NearestInteger, …) induce piecewise-fractional maps with integer coefficients. All these maps have natural extensions that can easily be described on an ad hoc basis.
We present a general framework for dealing with all these maps in a uniform way. The construction is geometric and well visualizable, exploiting both the interpretation of continued fractions as symbolic dynamics for the geodesic flow on the modular surface, and the projective duality between the hyperbolic plane and the de Sitter space.

This is a call for the participation of all DinAmicI to the Prima Giornata DinAmica, our first social meeting to be held on 25 November at the Gran Sasso Science Institute in L’Aquila.

There will be seminars by Mauro Artigiani, Anna Miriam Benini and Marcello Seri in the morning.  Whereas the afternoon will be devoted to the assembly of the DinAmicI, in which we will discuss possible directions of development of the group.

Here is the announcement of 1 yearly post-doc position funded by the ERC StG “Stable and Chaotic Motions in the Planetary Problem”, at the University of Naples “Federico II”, Department of Mathematics and Applications. Deadline: 10 October, 2016 (1:30 p.m.)

It is a pleasure to announce that our biennial meeting to be held in 2017, will take place in Rome in the week 5-9 June.

It will be sponsored by INdAM with the title

“Workshop INdAM - DinAmicI V - Modern Trends in the Ergodic Theory of Dynamical Systems”

and have agreed to be part of the scientific committee: Carlangelo Liverani, Yakov Sinai and Lai-Sang Young.

More information and a website will appear soon.

The workshop will be held at ICTP, Trieste, 19-23 June 2017. Particular emphasis will be devoted to the core topics which have benefited from the seminal contributions of Yakov Pesin: nonuniform hyperbolicity, dimension theory, thermodynamical formalism.

Speakers: Bunimovich, Buzzi, Denker, Dolgopyat, Hochman, A. Katok, S. Katok, Khanin, Ledrappier, Liverani, Luzzatto, Pesin, Pollicott, F. Rodriguez-Hertz, Sarig, Schmeling, Senti, Shub, Viana, Wilkinson, Zhang

Organizers: Dmitry Dolgopyat, Federico Rodriguez-Hertz, Omri Sarig. Local Organiser: Stefano Luzzatto.
