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.

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.

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, 2007
Location: Universitat de Barcelona
Web 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 motions
W. Bergweiler: Complex analysis and transcendental dynamics
B. Karpinska: Cantor bouquets in the iteration of entire functions and Hausdorff dimension
The 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 report
There 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:
The conference was 5 days long, arriving on Sunday afternoon and leaving on
Friday after lunch. There were a total number of 90 participants, 26 plenary talks of 50 minutes (see list
attached), and a session on open problems. There was also a poster session where most of the PhD students
attending presented a poster about their thesis work (see list attached). There was a chair person in charge of
introducing the speaker and the talk, at each of the morning sessions and another one for the afternoon
session. Each chair person introduced 2 talks. Attached you will find the schedule of the talks and of the
chair persons.
The talks were mostly on complex dynamics, with emphasis on the topological approach, by the top level
researchers in the field. Many new interesting results and open problems were presented. A small number of
talks where on real dynamical systems. The session of open problems (organized by Tan Lei and Carsten
Petersen) was also very successful, with a long list of speakers and participants presenting a problem related
to their work.
Details of people attending: There were 31 CODY members, attending the conference, from which 27
were funded by the CODY project. There were 3 ER's and 2 ESR's. Every CODY funded participant either
presented a talk, a poster, chaired a session or was in charge of the open problem session.

The quest for positive measure Julia sets
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 sessions
27 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

Details of the conference (including how the CODY funds were employed):
The school was attended by 21 delegates representing 4 nodes of the Network.
There were 22 lectures. Almost all participants gave talks, describing their recent results,
but there were also minicourses by Prof. Pertti Mattila on geometric measure theory and
Fourier analysis, by Prof. Michael Rams on Multifractal formalism for topologically
expanding maps and by Jörg Schmeling on multifractal analysis to metric number theory.
The funds supported by CODY are 4757,00 euros and employed to accommodation and hospitality.
Conference travel costs were met by the node to which the participants were affiliated.
There was a trip to visit the archeological Museum of Aiani which was organized and supported
by TEI of WM
