## Scientific General Events

The Alberta Topology Seminar (ATS) retreat will be held at the Goldeye resort outside Nordegg, AB.

This meeting focuses on unsolved problems in low-dimensional homotopy theory

and combinatorial group theory. These include Whitehead's Asphericity

Conjecture, the Andrews-Curtis Conjecture, Wall's Domination Problem in

dimension two, the relation gap problem, and the Eilenberg-Ganea Conjecture.

This seminar is in succession to similar conferences held in Luttach (Italy),

the Pacific Northwest, and Russia.The workshop format emphasizes detailed discussion of ideas in progress and

collaboration of the participants, from advanced graduate students to

early-career researchers to senior experts.Update 15 May 2009: The National

Science Foundation, Division of Mathematical Sciences, has awarded Portland

State University a grant for participant support (partial subsidies towards

travel expenses), and the Pacific Institute for the Mathematical Sciences has

granted supplementary support for the same purpose.**Symposium in Honour of David Brydges and Joel Feldman**

on the occasion of their 60th birthdaysThis is also part of the CRM-PIMS Thematic Group on Challenges and Perspectives in Probability.

This is a social event for the RWRE workshop.

PIMS is co-sponsoring a Canada/Korea Special Session on Algebraic Geometry and Topology, June 6-8, at the CMS Meeting in St. John's, Newfoundland.

The Langlands programme dominates the representation theory of linear algebraic groups over local and global fields. The theme of this workshop is the exploration of some of the geometric ideas appearing in recent advances in the Langlands programme, with an emphasis on results which apply to both function fields and number fields.

The goal of the conference is to promote cross-disciplinary research in statistical methods in engineering, science and technology. This is to be interpreted broadly to cover a wide range of application areas including environment, information and manufacturing sciences. The conference is intended to stimulate interactions among statisticians, researchers in the application areas, and industrial practitioners. It will provide a forum where participants can describe current research, identify important problems and areas of application, and formulate future research directions.

The general topic of the conference was the theory and application of

discrete structures and its goal was to highlight the most salient

trends in the field, which has close links to such diverse areas as

cryptography, computer science, large-scale networks and biology. The

conference brought together researchers from the various disciplines

with which discrete and algorithmic mathematics interact.Particular areas of interest were the following: graphs and digraphs, hypergraphs,

matroids, ordered sets, designs, coding theory, enumeration,

combinatorics of words, discrete optimization, discrete and

computational geometry, lattice point enumeration, combinatorial

algorithms, computational complexity, and applications of discrete and

algorithmic mathematics, including (but not limited to) web graphs,

computational biology, telecommunication networks, and information

processing.The goal of this workshop is to highlight emerging new topics in

spatial probability, and related areas where probabilistic ideas play

an important role. The emphasis is on types of questions and approaches

that are not largely based on existing techniques. We have invited

researchers with a variety of backgrounds, to help cross-fertilization

between areas. Some topics that the organizers have in mind are below,

although speakers have the freedom to choose what they find suitable.Combinatorial optimization problems with a stochastic component are a source of

challenging open questions. Examples are the traveling salesman problem

on a random set of points, other optimal path problems on random data,

and allocation problems. Heuristics from statistical physics often

suggest conjectures, open to investigation. Interacting spatial

processes has been an active area since the 1970s, with interesting

connections to other fields of mathematics such as random permutations,

and PDEs. Such processes with non-local interactions have not been

studied extensively. Interesting examples of deterministic processes

have been found, where randomness plays a role in the analysis, such as

crystal growth or sandpiles. These types of connections between

deterministic and random are likely to be the source of intriguing

questions in the future.
