Centro di Ricerca Matematica "Ennio De Giorgi" (Pisa, Italy)
16 April - 13 July 2007

The primary goal of this trimester is to provide a state of the art description of the subject of interaction between dynamics and number theory accessible both to young mathematicians wishing to do research in this area and to professional mathematicians from both disciplines interested in learning some of the most recent developments in the field.

In the framework of the research programme, it will take place the Clay Research Summer School at the Centro di Ricerca Matematica "Ennio De Giorgi" (Pisa, Italy) June 11th to July 6th 2007

The Clay Mathematics Institute will conduct its annual summer school for 2007 at the De Giorgi Mathematics Research Center in Pisa, Italy, from June 11th to July 6th 2007. The topic is "Homogeneous flows, moduli spaces, and arithmetic." Designed for graduate students and mathematicians within five years of their Ph.D., the program is an introduction to the theory of flows on homogeneous spaces and moduli spaces. These flows define concrete dynamical systems whose complex and subtle behavior leads to a rich theory, many interesting problems and conjectures, and a wealth of applications to number theory and geometry, e.g., equidistribution, diophantine approximation, rational billiards, and automorphic forms.

The school will consist of three weeks of foundational courses and one week of mini-courses focusing on more advanced topics. During the first three weeks there will be three long courses, of 14 lectures each, by Alex Eskin and Dmitry Kleinbock, Jean-Christophe Yoccoz, Manfred Einsiedler and Elon Lindenstrauss.

Organizing Committee: Manfred Einsiedler (Ohio State University), David Ellwood (Clay Mathematics Institute), Alex Eskin (University of Chicago), Dmitry Kleinboc (Brandeis University), Elon Lindenstrauss (Princeton University), Gregory Margulis (Yale University), Stefano Marmi (Scuola Normale Superiore Pisa), Peter Sarnak (Princeton University), Jean-Christophe Yoccoz: (College de France), Don Zagier (Max Planck Institut, Bonn and College de France).

Erwin Schrodinger Insitute, Vienna
February 26 - July 14, 2007

The Erwin Schrodinger Institute (ESI) will host a special semester devoted to AMENABILITY during the period end of February 2007 - mid-July 2007.

The organizers are:
Anna Erschler (Orsay, France),
Vadim A. Kaimanovich (Bremen, Germany),
Klaus Schmidt (Vienna, Austria)

The notion of amenability is a natural generalization of finiteness or compactness. It was introduced in 1929 by J. von Neumann (following the work of Hausdorff, Banach and Tarski; in 1955 M. M. Dye first called it amenability). Amenable groups are those which admit an invariant mean (rather than an invariant probability measure, which is the case for finite or compact groups). This classical notion has been generalized in many directions and currently plays an important role in various areas, such as dynamical systems, von Neumann and C*-algebras, operator K-theory, geometric group theory, random walks, etc.

The semester will be centered around several interconnected research subjects at the crossroads of Analysis, Algebra, Geometry, Dynamics and Probability. More specifically, we are going to discuss the following topics:

○ groups of intermediate growth, non-elementary amenable groups;

○ self-similar groups and iterated monodromy groups of rational maps;

○ graphed equivalence relations and amenability; L2 cohomology;

○ amenable groupoids; topological amenability of boundary actions;

○ amenability at infinity; Baum--Connes and Novikov conjectures;

○ amenability and rigidity; bounded cohomology;

○ amenable algebras;

○ quasi-isometric classification of amenable groups, geometricity of various group properties;

○ Dixmier's conjecture on characterization of amenability in terms of unitarizable representations;

○ generalizations of amenability: A-T-menabilty (Haagerup property); groups without free subgroups; superamenability;

○ random walks and other probabilistic models on amenable groups;

○ quantitative invariants of amenable groups: growth, isoperimetry, asymptotic entropy, etc.;

Anomalous Transport: Experimental Results and Theoretical Challenges
Physikzentrum Bad Honnef near Bonn, Germany
July 12-16, 2006

Scientific coordinators:
Rainer Klages, Queen Mary University of London, UK; Guenter Radons, TU Chemnitz, Germany; and Igor M. Sokolov, Humboldt-Universitaet zu Berlin, Germany.

Scope of this conference:

Anomalous transport phenomena such as sub- and superdiffusion, non-Gaussian probability distributions, aging and dynamical localization form a rapidly growing research area within nonequilibrium statistical physics. Understanding these processes demands for establishing new cross-links between non-Markovian microscopic correlations and unusual statistical properties on macroscopic scales. This requires to combine methods from dynamical systems theory, stochastic processes and disordered systems. The seminar will provide a unique opportunity to learn about topics ranging from mathematical foundations of anomalous dynamics to the most recent experimental results in this field. It attempts to initiate new cross-disciplinary collaborations between scientists from the above research areas and to foster fruitful interactions between theorists and experimentalists working on anomalous transport.

Scientific key topics:

Applications: Experimental results for anomalous transport under nonequilibrium conditions such as anomalous dispersion in flows, transport in porous media, aging in glassy systems, anomalous diffusion of biological cells and in cell membranes, surface diffusion, anomalous distributions in granular media and in plasma physics

Theoretical methods and models: nonhyperbolic dynamics, intermittent deterministic transport, disordered dynamical systems, Levy walks, Levy flights, random walks in random environments, dynamical phase transitions, classical dynamical localization, thermodynamic formalism, continuous time random walks, fractional calculus
