 DESCRIPTION\n\n\nIn this conference\, we are interested in the recent deve
 lopments around the mathematical theory of tilings and its recurrence prop
 erties\, which have a lot of connections with other areas like number theo
 ry\, dynamical system\, quasi-crystal\, computer science and discrete geom
 etry. We intend to focus particularly on the following areas:\n\nRecurrenc
 e properties of tiling and number theory\nThere has been a series of recen
 t developments on bounded remainder sets involving various methods (dynami
 cal\, topological\, number theoretical\, see [2\, 3]). We plan to discuss 
 and compare different approaches involved there. We would like to consider
  frequencies and recurrence properties in tiling spaces\, by focusing on v
 ariants of ergodic averages in this framework.\n\nSpectral property of til
 ing dynamical systems\nRelated to the first theme\, we shall discuss the l
 ong standing Pisot substitution conjecture\, the main remaining problem in
  this area. Pure discreteness of tiling is essentially the strongest recur
 rence property we can have\, which is equivalent to almost periodicity of 
 the associated point set (c.f. [6\, 1]). On this occasion we wish to merge
  people working in these areas to produce possible breakthroughs.\n\nAperi
 odic tile set and quasi-crystals\nAn aperiodic hexagonal monotile was foun
 d by Taylor-Socolar [5]. More recently the number of aperiodic tile set of
  Wang tiles reached its theoretical minimum 11 with Jeandel-Rao [4]. Their
  recurrence properties are quite fascinating and we shall discuss them as 
 models of quasi-crystals.\n\nReferences\n[1] S. Akiyama and J.-Y. Lee\, Al
