Systèmes dynamiques
Les organisateurs travaillent dans les systèmes dynamiques holomorphes. Le séminaire, bimensuel, porte sur les différents sujets connexes.
Organisateur(s) : A. ChéritatJour et lieu habituels : Jeudi 09H30, salle 207, batiment 1R2, 2eme etage
Le 26/02/2009 Sylvain Crovisier : Vers une caracterisation des dynamiques hyperboliques
La dynamique des diffeomorphismes hyperboliques d'une variete compacte est tres bien comprise. Dans cet expose, nous nous interessons a la classe des dynamiques non-hyperboliques. Cette classe comprend les diffeomorphismes que l'on peut perturber par bifurcation homocline et J. Palis a conjecture que ce sont les seuls. Nous presenterons des avancees recentes dans cette direction, obtenues avec Enrique Pujals.

REPORT ON WORKSHOP ENTITLED: Multifractal dimension and low dimensional systems
Dates: 08/01/2007 to 12/01/2007Location: The University of WarwickWeb Page: http://www.warwick.ac.uk/cody/workshop_UK_1.html
Details of speakers:
Name Talk TitleDavid Preiss Hausdorff and other dimensions
Mark Pollicott Teichmuller flows
Thomas Jordan Multifractal analysis and iterated function systems
Sebastian van Strien Physical measures in low dimensional systems
Richard SharpGwyneth Stallard
One talk each.
Details of the conference: The workshop consisted of four minicourses aimed at graduate students. These consisted of three one hour talks. The topics of the minicourses were on areas relating to low dimensional dynamical systems (paricularly Sebastian van Strien's talk) and multifractal analysis (Thomas Jordan andDavid Preiss). The fourth series, by Mark Pollicott, was on the Teichmuller flow which is a very popular research in dynamical systems. All the talks were introductory and tried to give an overview of the area rather than concentrating on new results.
On the last day of the meeting there were a couple of one hour talks by Richard Sharp and Gwyneth Stallard. Manfred Denker also gave an overview of results in non-uniformly hyperbolic dynamics. There were also short talks given by the graduate students who attended the meeting. Those who gave talks are indicated in the list of people attending. All together there were 34 participants (including those who gave minicourses) 24 of whom were students. As well as receiving funding from CODY the meeting was part of a series of similar meetings referred to as UK graduate schools in dynamical systems.

REPORT ON WORKSHOP ENTITLED ALGEBRAIC ACTIONS OF HIGHER RANK ABELIAN GROUPS AND INTRODUCTION TO RIGIDITY
Dates: 26 February - 8 March 2007Location: Banach Center, Warszawa, PolandWeb Page: http://www.impan.gov.pl/BC/conferences/07Katok.html
Speakers:
Name Talk TitleAnatole Katok PRELIMINARIES (approx. one lecture)
PRINCIPAL CLASSES OF ALGEBRAIC ACTIONS (approx. three lectures)ELEMENTS OF RIGIDITY THEORY (approx. two lectures)
Details of the conference (from the announcement):
The first goal of this course is to describe the objects of extensive recent and on-going research in rigidity theory for group actions, including necessary background from Lie theory and algebraic number theory. After that we prove model results in differentiable rigidity and measure rigidity which illustrate some of the methods used in this area. Along the way we will introduce necessary background from ergodic theory and hyperbolic dynamics.
The course will be accessible to students with a solid background in real analysis, advanced linear algebra and basic geometry/topology, including elementary properties of differentiable manifold. Basic acquaintance with ergodic theory will be helpful but not strictly necessary. No previous knowledge of Lie groups, algebraic number theory of hyperbolic dynamics is required.

CONFORMAL STRUCTURES AND DYNAMICS. THE CURRENT STATE-OF-THE-ART AND PERSPECTIVES
The Opening Conference of the CODY Network took place 11th – 15th June 2007. It was attended by 64 delegates representing all 9 nodes of the Network, together with representation from other affiliated institutions. Originally, 36 talks were planned but the programme was extended and 56 presentations were made throughout the five days of the conference. Almost all participants gave talks, some describing their thesis project, but most their recent results. This resulted in much more interaction between young participants than in most conferences.
A trip to the Royal Shakespeare Theatre was arranged. 28 participants purchased tickets to see a performance of Macbeth at The Swan Theatre. The network organised the transport to Stratford, which cost £207.90.
The accommodation costs, met by Warwick totalled £9640.86 and the hospitality for the conference cost £2563.54. The total cost of accommodation and hospitality was £12630.35.
Conference travel costs were met by the node to which the participants were affiliated. Warwick funded travel expenses for 6 people at a cost of £218.05. Six other participants funded their own expenses. One non-EU participant, Professor Alexandre Eremento, was funded by the Network, after obtaining permission from the EU Project Officer for his participation. One CODY employed researcher, Ferry Kwakkel, ESR, attended the meeting.
The conference was aimed to have talks and discuss the broad scientific aims of the network. Although there were minicourses on conformal analysis (Astala), multifractal analysis (Schmelling), and talks on conformal structures in mathematical physics (Astala, Levitz and others ...), for various reasons the meeting was attended disproportionally by those working in dynamics.
The level of talks and discussions was high. An additional feature of this meeting was that all PhD students also gave talks (of 10 to 20 minutes) describing their research topic and their results.
In conclusion, this meeting triggered many scientific discussions, hopefully new ideas, research links and certainly was also memorable in being intensive almost into the extreme (with talks on some days from 9am to 10pm).

“Workshop and ph.d. course on Symbolic Dynamics in Complex Dynamics”.
This combined workshop and Ph.d. course took place at the conference facility of RUC, Søminestationen in Holbæk, Denmark during 4 – 7 October 2007. It was attended by 30 participants representing 4 CODY nodes, Warwick, CNRS, Warsaw and RUC. The participants were 13 senior and 17 junior researchers, one of which is a CODY ESR, Kuntal Banerjee from the team CNRS.
There were 26 talks by 21 participants. For a full listing of lectures see the attached copy of the program (for abstracts please visit the conference webpage). The level of talks was high and it was particularly impressive to listen to the talks of the Ph.d. students, who generally gave very well prepared and clear lectures.
The setting at Søminestationen with integrated accommodation, dining and lecture room facilities is very well suited for this type of conference, intended to promote collaboration and to simultaneously disseminate both background and new mathematics. There were no special social events as such, but the venue was one long feast of mathematics providing good promises for future collaborations.
The conference was co-funded by CODY and the Danish Ph.d school Mathematics and applications. For participants from the CODY network, participating with at least one talk travel costs were met by the node to which the participant was affiliated, where as the RUC node paid for local costs. Other participants were either supported by the Ph.d school Mathematics or paid themselves.

CODY FALL SCHOOL 07 – TOPICS IN COMPLEX DYNAMICS
Dates: November 5-9, 2007Location: Universitat de BarcelonaWeb Page: http://www.imub.ub.es/fs07/
The school offered three main courses and several student presentations (see schedule attached).The three main speakers and courses (4.5hours each) were (see abstracts attached):
K. Astala: Holomorphic motionsW. Bergweiler: Complex analysis and transcendental dynamics B. Karpinska: Cantor bouquets in the iteration of entire functions and Hausdorff
dimensionThe level of the courses was initially introductory, but they covered plenty of material, up to discussing important applications and new results. The quality was very high and the attendance complete. The student talks were of various nature: some explained their thesis topics, others some newly obtained results. There was plenty of interaction between senior and junior researchers. The level of satisfaction among participants was reported to be very good.In conclusion, the meeting offered very good background mathematics to participants and exposed many open problems and hopefully new ideas. Many new aquaintances and research links were made during the school.Expense reportThere were a total of 24 participants, 20 of which were associated to the CODY project. Participants from outside Barcelona were lodged at the “Residencia d'Investigadors”, a researchers residence associated to the university and close by. The only exception was Prof. Christian Henriksen (DTU) who stayed in a different residence (“Campus del Mar”) of similar characteristics. Main speakers stayed in individual rooms while the other participants stayed generally in double rooms (there were a couple of exceptions, for logistic reasons). The project payed directly to the residence, the lodging of the CODY associated participants. Participants stayed up to a maximum of 7 nights. Those staying 7 nights, did so in order to have a Saturday night stay, and save in air travel. The total hotel bill amounts to 4.361 euros.With the exception of the speakers who were given per diem allowances, the project paid directly to a restaurant close by, the lunch of the CODY associated participants (bill attached). This was more economic than a per diem allowance. We did not cover dinners. The total restaurant bill amounts to 1.365euros.The main speakers were given a per diem allowance of 91.34 euros per day of stay in Barcelona. The total amount for the three main speakers was of 1.187.55 euros.

Details of the conference:
Adrien Douady was an extraordinarily inventive mathematician, and his work has had enormous influence on many fields of mathematics.
In his thesis, he developed the theory of Banach analytic spaces. This was done under the direction of Henri Cartan and was published in 1966. During the same year, he was invited to speak at the ICM at the age of 31. About 10 years later, he proved the existence of a local moduli space for an arbitrary compact analytic space, solving an important open problem. He published the complete solution in 1974.
Since 1980, his interests shifted to a vast domain called holomorphic dynamics: iterating holomorphic maps, studying their Julia sets and the Mandelbrot set. He is at the origin of the conjecture that the Mandelbrot set is locally connected. He developed the notions of polynomial-like maps, quasiconformal surgery, and parabolic implosion with his student John H. Hubbard. He is at the source of the proof by his students, Xavier Buff and Arnaud Chéritat, of the existence of polynomials having a Julia set of positive area.
This conference is dedicated to those fields most strongly marked by Adrien's work: complex analytic geometry and holomorphic dynamics. Many of the talks focus on Adrien's influence on these subjects as well as some of the more recent results.

Details of the conference (including how the CODY funds were employed):
There were 100 participants (plus some local not registered).There were 47 invited talks (40 minutes), most plenary, some in two parallel sessions27 short communications (20 min each, in two parallel sessions) and two posters.There was one problem session. Topics were mainly low-dimensional dynamics, ergodic theory and holomorphic dynamics (CODY tasks III.1, V.1, V.2, ).Top specialists in the world participated, in particular M.Misiurewicz himself, members of the scientific committee: Alseda, Denker, Llibre, Keane, Katok, Kolyada, and many young mathematicians from Poland and abroad. There were people from over 25 countries (European Union and also Ukraine, China, Japan, Chile, Brasil, Canada, USA), many of them involved in CODY. This was one of best conferences in dynamical systems in recent years. This meeting of the mathematicians from many countries and generations will imply in future a lot of fruitful cooperation. We plan editing of a volume of Fundamenta Mathematicae, an international journal, with papers related to the meeting. The total cost of the conference was about 30 000 Euro, CODY's contribution about 2500 Euro (3 people payed by CODY E, 8 by CODY F).

Details of the conference (including how the CODY funds were employed):
This was 3 weeks meeting: 2 weeks of school followed by 1 week workshop in which almost all participants (students and lecturers) of the school took part and some more invited speakers arrived. The school had 6 minicourses and some complementary seminars/exercises. They were on a very high scientific level, by top class mathematicians. Altogether there were about 60 participants (including about 32 PhD students), most of them staying the whole 3 weeks period. Nevertheless the number of PhD students was much smaller than expected, probably because of unsufficient advertising.
Lecture Notes will be published, probably by AMS. Some notes are already available at the web page
