Résumé: In recent years, the most interesting developments in the theory of two-dimensional critical phenomena have emerged from a developing field that might be called Conformal Probability Theory which complements the extensive work (starting from the 1970's) in the Physics community on Conformal Field Theory. Substantial progress has been made in understanding the random fractal geometry of such two-dimensional systems as critical percolation and critical Ising models and their relation with such classic probabalistic objects as the frontier of two-dimensional Brownian motion. Among the topics to be treated in this workshop are: SLE and its Extensions, Critical and Near-Critical Scaling Limits, Gaussian Free Field, Coulomb Gas Methods, Relation to Conformal Field Theory and Quantum Gravity.

Résumé: The aim of this permanent school is to introduce undergraduate and Ph.D. students in Mathematics and Physics, as well as post-doctoral researchers, in a recently emerged area of Mathematics and Theoretical Physics: Secondary Calculus. A Diffiety is a new geometrical object that properly formalizes the concept of the solution space of a given system of nonlinear PDEs, much as an algebraic variety does with respect to solutions of a given system of algebraic equations. Secondary Calculus is a natural diffiety analogue of the standard calculus on smooth manifolds, and as such leads to a very rich general theory of nonlinear PDEs. Moreover, it appears to be the unique natural language for quantum physics, just as the standard calculus is the natural language for classical physics.

Résumé: Tiling problems have a long tradition in combinatorics and in statistical mechanics. One of the central problems is understanding the statistical structure of the patterns obtained when randomly tiling a large domain. As noticed by N. Elkies and J. Propp a decade ago, random tilings of a large planar domain may exhibit phase segregation; the density of tiles has a smooth (non-constant) variation in some regions of the domain in coexistence with a frozen region where the density of tiles is constant. In the corresponding surface picture the frozen region corresponds to a facet of constant slope while in the complement one has a rounded surface.

Résumé: This workshop will bring together researchers interested in the topology of stratified spaces. It will focus roughly on four topics: topology of complex varieties, signature theory on singular spaces, and intersection cohomology, and mixed Hodge theory and singularities. Aside from talks on current research, there will be a series of introductory lectures on these themes. These talks will be aimed at strengthening the connections among the various topology research groups and the connections between topology researchers and researchers at the program on Analysis of Singular Spaces, running concurrently.

Résumé: This workshop, sponsored by AIM and the NSF, has the goal of providing a description of $GL_3$ automorphic forms and their $L$-functions amenable to analytic number theorists and to explain the various approaches available to perform harmonic analysis on these spaces. A second objective will be to discuss the extension of some of the important tools existing in the $GL_2$ theory to the $GL_3$ context: a typical example is Kuznetzov's formula. A third objective will be to list some important problems known for $GL_2$ and to identify the main obstructions to the extension of these to $GL_3$: typical problems are non-vanishing problems for central values of L-functions and subconvexity problem. To achieve these goals we plan to bring together analytic number theorists and specialists from the theory of automorphic forms and related fields who are interested in analytic questions.

Résumé: There have been some very rapid changes to the interactions of algebra, geometry and analysis in recent years, many prompted by new mathematical ideas coming from physics. Novel algebraic structures have been invented, new methods for calculating invariants of geometric objects found and radical developments in noncommutative algebra and analysis have occurred under the influence of string theory and many body quantum physics. This meeting is to review these rapidly developing areas, so as to provide an additional attraction for international visitors who may be interested in attending the AustMS/NZMS convention. It also provides opportunities to postgraduate students and postdoctoral fellows to access these latest developments and to relate them to their own research.

Résumé: The recent progress in topology has shed light on many deep connections between algebraic topology and the theory of braids. A successful program on Braids was organized in May-July, 2007.

Résumé: TOPOLOGY, C*-ALGEBRAS, and STRING DUALITY May 18 - May 22, 2009 Opening reception on the evening of May 17 at Texas Christian University, Fort Worth, TX Principal Lecturer: Jonathan Rosenberg (Univ. of Maryland) Some of the most exciting current research in geometry and topology has been motivated by problems in mathematical physics in general, and string theory in particular. Physicists are still divided concerning the usefulness of string theory as a ``unified field theory,'' uniting our understanding of all the fundamental forces of nature. However, even if string theory should turn out not to be fully confirmed by experiment, the fascinating and beautiful mathematics it has generated is expected to retain its mathematical value. The subject of the conference will involve a number of such ``spin-offs'' of string theory into pure mathematics, and the way they connect with other topics in topology and operator algebras that were initially developed for other purposes.

Résumé: The main scientific topics will be presented on the conference are: infinite dimensional holomorphy, topological tensor products, Banach space theory, operator theory; general topology; set-theoretic topology; geometric and infinite dimensional topology.

Résumé: The conference will cover the following subjects : ramification theory, vanishing cycles, rigid geometry, arithmetic D-modules, geometric and p-adic aspects of the Langlands Correspondence and related topics.

Résumé: The aim of this conference is to bring together researchers from all aspects of finite fields: theory, computation and applications. Previous meetings have been in Las Vegas (USA), Glasgow (Scotland), Waterloo (Canada), Augsburg (Germany), Oaxaca (Mexico), Toulouse (France) and Melbourne (Australia). As in previous years we intend to publish conference proceedings with one of the major scientific publishers.

Résumé: In the 1980's Grothendieck formulated his anabelian conjectures that brought to an hitherto-unexplored depth the interaction between topology and arithmetic. This suggested that the study of non-abelian fundamental groups could lead to a new understanding of deep arithmetic phenomena, including the arithmetic theory of moduli and Diophantine finiteness on hyperbolic curves. A certain amount of work in recent years linking fundamental groups to Diophantine geometry intimates deep and mysterious connections to the theory of motives and Iwasawa theory, with their links with arithmetic problems on special values of L-functions such as the conjecture of Birch and Swinnerton-Dyer. The goal of this programme is to investigate the ideas and problems of anabelian geometry within the global context of mainstream arithmetic geometry.

Résumé: The goals of the 2009-2010 program at MSRI are to. I. Promote the cross-pollination of ideas between different areas of symplectic and contact geometry; II. Help assess and formulate the main outstanding fundamental problems and directions in the field; III. Lead to new breakthroughs and solutions of some of the main problems in the area; IV. Discover new applications of symplectic and contact geometry in mathematics and physics; V. Educate a new generation of young mathematicians, giving them a broader view of the subject and the capability to employ techniques from different areas in their research. To achieve these goals, the program will concentrate on three broad, interrelated themes that encompass many of the modern trends in symplectic geometry: algebraic structures associated to holomorphic curves; symplectic and contact geometry in low-dimensional topology; and symplectic topology and dynamics.
