In recent years a large number of scaling laws in geomorphology have been found to be equivalent to only two scaling laws. Recent results on river meanders indicate that there may be only one universal scaling law, implying all the others. Moreover, recent theoretical results on turbulent flow in rivers indicate that turbulent flow is the source of the universal scaling of river basins and river networks.

These results provide a key to the understanding of the fundamental structure of the surface of the earth, that layers of complexity such as tectonic uplift, earthquake rifts and the action of glaciers can then be added to. It provides a way of quantifying transport of water, sediments and chemicals over the surface and exchanges of dissolved chemicals between the water and the atmosphere. In particular this seems to provide a method to quantify the transfer of carbon dioxide from rivers to the atmosphere. This workshop will explore why and how this transport due to turbulent flow takes place and is optimal.

Other transport such as transport of magma in volcanoes will also be covered and how similar ideas can be used to identify and quantify transport in social networks and economics.

The CRM and INRIA has had a longstanding cooperation. On August 24, 1973, a cooperation agreement was signed between M. L'Abbé (VP Research, U de M), L. Le Cam (director of the CRM) and the academician J. L. Lions (director) of the LABORIA of the Institut de Recherche d'Informatique et d'Automatique (IRIA – initial name of INRIA). In 2003 the "Équipe INRIA associée à l'étranger ACE" (Aérosols, Cœur, Endoprothèses - Aerosols, Heart, Endoprotheses) was created by INRIA with the participation of the CRM, GIREF and the University of Ottawa and later expanded to include Taiwan. In May 2005 a Spring School and a Workshop on Mini invasive procedures in Medicine and Surgery took place in Montreal and was cosponsored by the CRM, INRIA, and MITACS. The cooperation of the CRM with INRIA was expanded in 2005 by the exchange and cooperation agreement with the Quebec government (FQRNT) as part of its educational and industrial strategies. Following the recent visit of the president of INRIA, Michel Cosnard, at MITACS headquarters at the end of July 2007, this meeting is a timely opportunity to foster cooperative links between INRIA, MITACS, and the Canadian Institutes building on the cooperation record of the CRM.

This meeting is preceded by the Spring School "5th Montreal Scientific Computing Days", April 30 - May 2, 2008.

This is the next in a series of triennial colloquia devoted to the mathematical legacy of Lars Ahlfors and Lipman Bers. The core of this legacy concerns geometric function theory, quasiconformal mapping, Teichmüller theory and Kleinian groups, hyperbolic manifolds, and partial differential equations including Schram/Stochastic-Loewner-Evolution/Equations. In addition the work of Alhfors and Bers has had an impact on algebraic geometry, mathematical physics, dynamics, geometric group theory, number theory and topology.

The Fourth Ahlfors-Bers Colloquium is sponsored by by the National Science Foundation, Rutgers University Newark and the Department of Mathematics and Computer Science of Rutgers - Newark.

The Canadian Young Researchers Conference in Mathematics and Statistics (CYRC) is an annual event that provides a unique forum for young mathematicians across Canada to present their research and to collaborate with their peers.

All young academics involved in research in the mathematical sciences are invited to give a scientific talk describing their work and to attend talks on a host of current research topics in mathematics and statistics. Participants will have the opportunity to build and strengthen lasting personal and professional relationships, to develop and improve their communication skills, and to gain valuable experience in the environment of a scientific conference.

The school is aimed at providing courses for advanced graduate students and postdoctoral researchers from all over the world who are interested in mathematical and physical aspects of quantum gravity and their impact on current research in fundamental science. There will be five series of lectures by highly distinguished scientists on various aspects of modern quantum field theory and quantum gravity:

QUANTUM GRAVITY AS A SUM OVER SPACETIME HISTORIES - Jan Ambjorn (Niels Bohr Institute)
SELECTED MATHEMATICAL ASPECTS OF MODERN QUANTUM FIELD THEORY - Peter Bouwknegt (Australian National University)
CURRENT TRENDS IN NON-COMMUTATIVE GEOMETRY - José Gracia-Bondia (Universidad Complutense de Madrid and University of Costa Rica)
TOPOLOGICAL STRINGS AND GROMOV-WITTEN INVARIANTS - Albrecht Klemm (University of Wisconsin-Madison)
QUANTUM INVARIANTS AND QUANTUM MODULI SPACES - Nicolai Reshetikhin (University of California, Berkeley)

The human body is a fascinating transport system, in which organs must exchange nutrients, water, oxygen, and waste to maintain life. To allow rapid access of a large amount of oxygen to the whole body, the respiratory and cardiovascular systems exhibit extremely complex geometrical structures. In the course of evolution, these organs have been optimized for efficient transfer under various and sometimes unknown constraints. For instance, the respiratory systems in mammals and birds are very different, although they are both highly efficient. At the same time, the efficiency may be substantially reduced by deteriorations, aging, or diseases. A better understanding of the optimal transport in these systems is a key for curing diseases, drug delivery, and design of artificial implants.

This workshop will bring together internationally renowned experts as well as postdocs and students with research interests in the respiratory and cardiovascular systems, as well as in optimal transport. Participants will include mathematicians, physicists, physiologists, medical doctors, engineers, and computational fluid-dynamicists. The workshop will allow all participants to gain a perspective of cross-disciplinary aspects of the same fundamental topic from the experts in the field and provide an opportunity to establish new research collaborations.

The encounters between the fields of analysis, geometry and topology are widespread and often provide major impetus for breakthroughs in these domains. Impressive examples include the exciting new developments in low dimensional topology related to invariants of links and three and four manifolds; Perelman's spectacular proof of the Poincare conjecture; and also the recent advances made in algebraic, complex, symplectic and tropical geometry.

This conference invites distinguished speakers representing major directions in analysis, geometry and topology who, through their work, have contributed to establishing relations between these fields.

It also provides a pleasant opportunity to express admiration for the work and mathematical interests of Oleg Viro who will be celebrating his 60th birthday this year. Oleg Viro has made invaluable contributions to Swedish research by complementing the country's long standing strong tradition of analysis with his own renowned expertise in topology and areas of geometry: subjects not previously widely studied in Sweden.

In recent years, applications of algebraic geometry have surfaced in multiple directions, from classical kinematics to mathematical biology, from control theory to geometric modeling and computer graphics. Powerful new techniques in numerical algebraic geometry, with their software implementations, are more and more becoming part of the standard toolbox of algebraic geometers, together with symbolic methods and their software realizations. Numerical and classical techniques are complementing each other in solving problems of both pure and applied nature. This conference is an opportunity for experts and practitioners of this multifaceted world to come together and share recent developments, problems, and future directions.

Numerical algebraic geometry would not have risen to center stage if it were not for the work of Andrew J. Sommese, Vincent J. and Annamarie Duncan professor of mathematics at the University of Notre Dame, and this conference is a fitting celebration for his 60th birthday.

The invited speakers will report on some of their recent research on various aspects of Analysis. Spaces of analytic functions such as Hardy, Dirichlet and Bergman, and operators acting on them such as Hankel, Toeplitz and composition operators, will constitute a principal theme.
