Tilings and Tessellations is a mathematic school supported by the CIMPA. It is primarily dedicated to young researchers and graduate students (motivated undergraduated students are also welcome) in mathematics from Iran and neighbor countries (grants for travel and accomodation are provided). About 60 hours of lectures on tilings shall be given by international researchers. Tilings offer a connection between combinatorics, computability, discrete geometry, dynamical systems and probability theory. Tilings are also related to the tessellations that embellish islamic architecture, and wider audience lectures shall be given on this subject.
