This workshop, sponsored by AIM and the NSF, will be devoted to deciphering the mysterious connections between the following objects:

- Garside monoid structures for Coxeter and braid groups, and the associated "lattices of non-crossing partitions"
- the cluster algebras of Fomin and Zelevinsky, and the associated polytopes known as "generalized associahedra"
- ad-nilpotent ideals within Borel subalgebras of semisimple Lie algebras, or equivalently, subsets of pairwise incomparable positive roots

The main topics for the workshop are

- Garside monoids and non-crossing partitions
- Non-crossing partitions and free probability
- Cluster algebras and generalized associahedra
- Ad-nilpotent ideals in Borel subalgebras

The workshop will differ from typical conferences in some regards. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and working sessions.

Invited participants include C. Athanasiadis, D. Bessis, T. Brady, N. Brady, F. Chapoton, R. Charney, B. Collins, R. Corran, J. Crisp, P. Dehornoy, S. Fomin, F. Goodman, J. McCammond, J. Meier, A. Nica, N. Reading, V. Reiner, M. Shapiro, P. Sniady, E. Sommers, H. Thomas, M. Wachs, K. Whittlesey, and A. Zelevinsky.
