Combinatorics workshop participants<br />

sentations and three invited talks from Robin Thomas<br />

(Georgia <strong>Institute</strong> <strong>of</strong> Technology), Claude Tardif (Royal<br />

Military College) and Jim Geelen (Waterloo).<br />

Since 2003, the Peter Rodney Memorial Book Prize has<br />

been awarded to the best student presentation. This year’s<br />

winner was Lap Chi (<strong>Toronto</strong>) for his talk “Packing Steiner<br />

Trees and Forests”.<br />

There were approximately 40 participants at the workshop.<br />

Speakers:<br />

The <strong>2005</strong> Great Lakes Geometry Conference<br />

April 30–May 1, <strong>2005</strong><br />

Held at Perimeter <strong>Institute</strong><br />

Organizers: Hans U. Boden (McMaster), Finnur Lárusson<br />

(UWO), B. Doug Park (UWO) and Mainak Poddar (Waterloo)<br />

Scientific Committee: Ronald Fintushel (Michigan State),<br />

Robert Myers (Perimeter), and Yongbin Ruan (Wisconsin)<br />

The Great Lakes Geometry Conference (GLGC) began in<br />

1999 at the <strong>University</strong> <strong>of</strong> Wisconsin under the leadership <strong>of</strong><br />

Yongbin Ruan. Since then, the conference has met at several<br />

major universities in the Great Lakes region, including<br />

Northwestern, Notre Dame, Michigan, and Michigan State.<br />

This year, the conference came to Canada for the first time<br />

and was hosted at Perimeter <strong>Institute</strong> for Theoretical Physics<br />

in Waterloo, Ontario.<br />
