122. SIMUW 2005: Combinatorics combinatorics is the art of counting how many ways are there to do something? From this humblesounding beginning, combinatorics expands in a huge http://research.microsoft.com/~cohn/simuwdesc05.html

Combinatorics Summer Institute for Mathematics at the University of Washington, 2005 Henry Cohn Combinatorics is the art of counting: how many ways are there to do something? For example, how many different ways are there to make change for $1.00, i.e., to break up a dollar into coins? From this humble-sounding beginning, combinatorics expands in a huge number of directions. It turns out that a number of powerful principles underlie much of the field, and gather apparently disparate problems into a unified theory. This theory applies to many different sorts of mathematical objects. Furthermore, it has connections with many other fields, ranging from probability to computer science. In this course, we will study several different sorts of combinatorics, including enumerative combinatorics and graph theory. The focus will be on solving challenging problems, since one of the beauties of combinatorics is that frequently, once one has absorbed a certain principle, problems that previously seemed impossible suddenly become quite doable.

Conferences and Workshops 13th Ontario Combinatorics Workshop May 6-7, 2004, Royal Military College, Kingston Queen's University Royal Military College The 13th Ontario Combinatorics Workshop will be hosted by the Royal Military College and Queen's University on May 6-7, 2004, at the Royal Military College. The meeting is intended to be informal; participants are encouraged to present a short talk (30 min.) on their current or future research. Graduate students, postdocs and young researchers are especially encouraged to talk in this comfortable and friendly meeting! Supervisors, please encourage your graduates students to attend and speak. There are limited support funds available for students from out of town who speak at the workshop. All areas of combinatorics and discrete mathematics are included! Opportunities for discussion and joint research will be emphasized. There is no registration fee. There will be two plenary speakers: Shlomo Hoory (University of Toronto), and Bruce Reed (McGill University). The remainder of the two days is reserved for contributed talks.

My research is mainly in the areas of number theory and combinatorics; I also have interests in algebra and theoretical computer science. I am a member of the Centre for Interdiscipinary Research in Computational Algebra (CIRCA) Teaching I have no undergraduate lecture courses this session. During the session 2003-2004, I taught two courses: the Honours course Groups-MT4603 and the Level 2 course Linear Algebra-MT2001 Course materials for Groups-MT4603 may be found here , while course materials for Linear Algebra-MT2001 may be found here Brief career history I obtained my PhD in the Department of Mathematics at the University of Glasgow . I was a postgraduate student there from October 1999 to December 2002. I spent the first year of my postgraduate studies working on Drinfeld modules under the supervision of the late Professor Bob Odoni . Subsequently, I moved into the area of Galois fields, and worked on this topic for my PhD thesis, supervised by

A Research Training Network of the European Community Algebraic Combinatorics in Europe (ACE) (September 1, 2002 - August 31, 2005) Overview The Teams Programme Open Positions Activities ... An article about the network Project overview When a variety of fields meets combinatorics The origins of Algebraic Combinatorics lie in the desire to advance combinatorial theory from the state as a ``bag of various, isolated tricks" (as it is often seen) to an organised body of algebraic theories that bring order into seemingly disorder. Of course, Gian-Carlo Rota's name has to be mentioned here. He started this development by the introduction of the theory of , and the systematical use and development of umbral calculus in the 60's and 70's. Since then many more algebraic theories have evolved and are still being developed, e.g., theory of "species" and "generatingfunctionology" combinatorial representation theory symmetric functions and tableau calculus combinatorial topology (to mention just a few), bringing increasing insight in and understanding of combinatorial structures. Today, Algebraic Combinatorics concerns itself with the study of combinatorial problems arising from other branches of mathematics and, on the other hand, with the application and use of techniques coming from other parts of mathematics to combinatorial problems. At the heart of the subject there is the development of algebraic theories for the solution of such problems. The implied interactions with other fields are mutually beneficial and concern particularly

Text only Department of Mathematics Home Research Home Research ... Contact Both number theory and combinatorics are part of what is called discrete mathematics, which has important applications in computer science and information technology, as well as an intrinsic elegance and fascination for mathematicians, professionals and amateurs alike. Number theory In combinatorics one is usually concerned with a finite set with some additional structure (e.g. a projective geometry, a graph or a block-design), and seeks to relate it to some already-known set of the same kind, or perhaps to show that certain structures can (or cannot) be imposed on a given set. Another type of question is the enumeration of particular kinds of structures (e.g. how many connected graphs are there on n vertices?). Current topics of interest in the department include: combinatorial design theory; automorphism groups of graphs and designs; Hadamard matrices and symmetric designs and their classification; applications of combinatorics to computer graphics.

This talk is about the mathematical foundations of circuit theory. It outlines an exposition of elementary DC circuit theory from the point of view that circuits (not just elements) are voltage-current mappings. Rather than focusing on the internal details of circuits as is customary in introductory texts, the focus is on their external behaviour: a "black box" view. This change in focus enables the definitions of the theory to be stated precisely and the theorems to be proved rigorously. An application to the dissection of rectangles into right-angled isosceles triangles will be presented.
