タイトル：Aperiodic Order � a tour through Logic, Topology, Dynamics and Continued Fractions

アブストラクト：
Aperiodic Order is the term used to discuss often geometric phenomena which are not perfectly symmetric, yet have strong global structure and often approximate symmetries. The most well known examples are the aperiodic tilings of Penrose and others: tilings of the plane that never repeat, yet are highly structured and very far from being random.
This talk will be a gentle introduction to some of the topics arising in the field of Aperiodic Order. After sketching its historical inception, we shall concentrate of the use of topology as a tool to think about it, linking to aspects of dynamics, ergodic theory and even continued fractions.
