This meeting will be a continuation of the successful workshops held in Kingston in 2004, and in Ottawa in 2005. The main achievement of the past events has been that they have established an on-going dialog between two separate research communities who had been using similar techniques to study different mathematical problems. The two groups are algebraic combinatorialists working on the representation theory of symmetric groups, and commutative algebraists studying resolutions and inverse systems.

The connections between these topics were highlighted in a successful meeting that took place in January 2004 at Queen's University in Kingston. In this meeting, through a series of expository lectures by Tony Geramita and François Bergeron, among others, it was made evident that interesting special cases of the notion of Macaulay's inverse systems of Commutative Algebra are essentially the same objects as coinvariants spaces studied in Algebraic Combinatorics and Representation Theory.

This year's meeting will continue in the same tradition. The main speakers are:

François Bergeron (UQAM)
Nantel Bergeron (York University)
Mats Boij (KTH, Stockholm)
Tony Geramita (Queen's Univerity)
Christophe Reutenauer (UQAM)
