Quasi periodic tiling and related topicsQuasi periodic tiling and related topics

Followed by the one held last year under the same title, a short term cooperative research at Research Institute for Mathematical Science (RIMS), organized by Shunji Ito and Shigeki Akiyama will take place on 3-6 June, 2002. Anyone interested are welcome.
