• Inaugural Conference of the Laboratory Fibonacci

5 March 2012 – 8 March 2012

 The Laboratory Fibonacci is a new research unit in mathematics hosted by the Centro De Giorgi in Pisa, fruit of an agreement between the French National Centre for Scientific Research and the Scuola Normale Superiore di Pisa. To celebrate its birth, a meeting will take place at the Centro de Giorgi, from the afternoon of March 5 to March 8. The first afternoon will be devoted to contributions from Italian and French authorities and two general talks. The rest of the meeting will cover three topics where the Italy-France mathematical cooperation is particularly successful and developed, namely dynamical systems, linear and nonlinear wave equations and optimal mass transportation.

      Speakers: Thomas Alazard,  Sylvain Arlot,  Patrick Bernard,  Jérôme Bertrand, Giuseppe Buttazzo, Guillaume Carlier, Alain Chenciner, Scipio Cuccagna, Jacopo De Simoi, Daniele Del Santo, Luca Fanelli, Albert Fathi, Jacques Féjoz, Nicola Gigli, David Lannes, Luca Marchese, Carlos Matheus, Guy Métivier, Laure Saint-Raymond, Yannick Sire, Jean-Christophe Yoccoz.

Candidacy formalities 2011

27 June, 2011 – 24 July, 2011

Będlewo – Polska

WEEK 1: Tutorial preparatory courses, Jun 27 -July 2
Audience: about 30-35 Ph.D students from all over the world with significant Polish participation

WEEKS 2-3: Advanced summer school, July 4-16
Audience: about 60-70 participants including those from week 1, plus advanced graduate students, recent Ph.D’s and mathematicians of various ages interested in various aspects of the subject

WEEK 4: Workshop for 100 participants, July 18-23

The main aim of the summer school is to provide to participants modern methods of dynamical systems oriented to applications in analysis, geometry and number theory. This area is one of best developing in modern mathematics; one of the leaders of this area, Elon Lindenstrauss, was awarded Fields Medal during the last ICM (India, Hydebarad). The concluding workshop will sum up the current scientific knowledge of the subject.

First week courses are aimed at the beginning and middle years Ph.D. students who have good knowledge of real analysis and basic topology but may not have sufficient familiarity with basics of dynamics and the theory of Lie groups. The goal is to bring participants at the level necessary to participate in the advanced courses.

In addition to the participants of week 1 advanced courses are aimed at advanced graduate students, your researchers working in dynamical systems and related areas as well as to mathematicians of all ages interested in various aspects of the subjects. There is no requirement to take all advanced courses simultaneously. In fact it is expected that each participant will participated on the average in four courses out of six.

Financial support toward local expenses for a restricted number of participants will be available (REGISTRATION FORM). If you need any additional information contact one of organizers.

Principal subjects for the school courses:

TUTORIALS, Week 1

Omri Sarig:
Introduction to ergodic theory,

Francois Ledrappier: (to be confirmed)
Introduction to smooth ergodic theory,

Alexander Gorodnik:
Basics of Lie groups, Discrete subgroups and arithmetic groups for dynamicists,

Each course is expected to run daily with a double lecture: two parts 45-50 minutes with a break.
It is planned a seminar run by A. Katok in the evenings during the first week to help tying loose ends.

ADVANCED COURSES

Livio Flaminio:
Introduction to the theory of unitary group representations and its applications to dynamics
Weeks 2-3

Michael Hochman:
Interactions between ergodic theory and fractal geometry
Weeks 2-3

The Clay Mathematics Institute presents the Clay Research Award annually to recognize major breakthroughs in mathematical research. Awardees receive the bronze sculpture “Figureight Knot Complement VII/CMI” by sculptor Helaman Ferguson.

Yves Benoist and Jean-François Quint

For their spectacular work on stationary measures and orbit closures for actions of non-abelian groups on homogeneous spaces. This work is a major breakthrough in homogeneous dynamics and related areas of mathematics. In particular, Benoist and Quint proved the following conjecture of Furstenberg. Let H be a Zariski dense semisimple subgroup of a Lie group which acts by left translations on the quotient of G by a discrete subgroup with finite covolume. Consider a probability measure m on H whose support generates H. Then any m-stationary probability measure for such an action is H-invariant.

Jonathan Pila

For his resolution of the André-Oort Conjecture in the case of products of modular curves. This work gives the first unconditional proof of fundamental cases of these general conjectures beyond the original theorem of André concerning the product of two such curves. The foundational techniques that Pila developed to achieve this breakthrough range from results in real analytic geometry which give sharp upper bounds for the number of rational points of bounded height on certain analytic sets, to the use of O-minimal structures in mathematical logic.

This conference is the fifth in a series of triennial colloquia devoted to the mathematical legacy of Lars Ahlfors and Lipman Bers. The core heritage is in geometric function theory, quasiconformal mapping, Teichmüller theory and Kleinian groups, hyperbolic manifolds, and partial differential equations including Schramm/Stochastic-Loewner-Evolution/Equations. Today we see the influence of Ahlfors and Bers on algebraic geometry, mathematical physics, dynamics, probability, geometric group theory, number theory and topology.

Beyond Uniform Hyperbolicity 2011

This conference on Dynamical Systems will be held at the Centre International de Rencontres Mathématiques (C.I.R.M.) in Marseilles in June 2011 (from 5th to 17th).

In keeping with the previous meetings on global dynamics beyond uniform hyperbolicity (Beijing 2009, Chicago 2006, Buzios 2003, Chicago 2001), the focus will be on the global qualitative study (topological and ergodic) of differentiable dynamical systems, especially diffeomorphisms and vector fields, that are not uniformly hyperbolic. Among the main topics to be covered are:

1. Hyperbolicity:
   1. Partial hyperbolicity    (Classification, rigidity, )
   2. Nonuniform hyperbolicity
   3. Singular hyperbolicity
   4. Lyapunov exponents
   5. Dimension
   6. Statistical properties
2. Global & Semi Local Properties:
   1. The C1‐topology
   2. Bifurcations
3. Other topics:
   1. Symbolic extensions
   2. Teichmuller space dynamics
   3. Actions of discrete groups on manifolds

   Our aim is to form a group of 80 mathematicians including of the main international actors in these subjects, as well as young mathematicians and students. We plan to have a few mini-courses and plenary lectures, so that a large part of the time will be devoted to informal discussions. A number of lecture rooms will be available to the participants for more specialized sessions. The CIRM is located in a wonderful place that offers many possibilities for discussing math during a walk in the famous “calanques”. It also features a research library and computer services (see the CIRM web site here).

The description is perfect !!!

A Week in the Life of a Mathematician

‘Twas on a Monday morning I had a bright idea,
I was lying in the bath tub and the strategy seemed clear,
For a problem posed by Erdös back in nineteen forty nine,
On sequences dilated into subsets of the line

‘Twas on a Tuesday morning I jotted down my thoughts,
I covered backs of envelopes with surds and aleph noughts.
After several cups of coffee I began to feel inspired,
And a lengthy calculation gave the answer I desired.

‘Twas on a Wednesday morning I wrote the details out.
My lemmas and corollaries left little room for doubt.
I filled up many pages just to get the logic right,
And with epsilons and deltas I made it watertight.

‘Twas on a Thursday morning I typed the paper up,
With “slash subset” and “slash mapsto” to say nothing of “slash cup”.
My LaTeXing was perfect, printed out it looked so good,
Should I send it to the Annals? I rather thought I would!

‘Twas on a Friday morning I read the paper through,
I checked out every detail as good authors ought to do.
At the bottom of page twenty in an integral I found,
I’d divided through by zero and the proof crashed to the ground.

On Saturday and Sunday I was too depressed to care,
So ’twas on a Monday morning that I had my next idea.
