## Scientific General Events

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**

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.Abstract harmonic analysis and related topics (Banach algebra, operator spaces, geometric functional analysis, etc.).

The ties between combinatorics and probability run so deep that for

many deep and interesting problems, it is nonsensical to try to assign

one category or the other. The subject of this workshop is these sorts

of problems, many of which in fact come from the theoretical computer

science and statistical physics communities. Most of the speakers

straddle two or several of these areas in their research. We expect the

workshop to both expose participants to cutting edge research in

combinatorics and probability, and, importantly, to lead to fruitful

discussions and the opening of new avenues of research.**Alberta Colleges Mathematics Conference - May 1 & 2, 2009**This annual conference presents talks on teaching issues specific to college math course offerings and provides an opportunity to meet colleagues from Alberta's post secondary institutions, discuss teaching, technology and curriculum and to share perspectives on experiences and common interests of mathematics in Alberta.
