The Conference on Aperiodic Structures will be devoted to structure and related properties of quasicrystals and modulated structures (both theoretical and experimental results).

• Physical properties of quasicrystals
• Theory of quasicrystals
• Higher-dimensional analysis and symmetry
• Neutron diffraction and symmetry analysis of modulated structures
• Diffraction data collection and analysis
• Other aperiodic systems

The Conference is a satellite meeting of the 20^th European Crystallographic Meeting held in Cracow from 25^th to 31^st August 2001. The scientific program is planned to consist of tutorial invited talks, oral and poster presentations. We aim particularly to give chance to young scientists or students to meet the well-known specialists. We would also like to encourage presentations of new results from young researches. The conference language will be English.

The social program will include a conference excursion and a conference dinner. Program for accompanying persons will be arranged.

The Conference will take place in Krynica near Cracow. Krynica is a small resort town in the Beskidy Mountains. The conference will take place in the university guesthouse "Baœka". Participants will be logged there either.
