DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OWNS/123/">O
 verlap algorithm for general S-adic tilings</a>\nby Yasushi Nagai (Shinshu
  University) as part of One World Numeration seminar\n\n\nAbstract\nWe inv
 estigate the question of when a tiling has pure point spectrum\, for the c
 lass of $S$-adic tilings\, which includes all self-affine tilings. The ove
 rlap algorithm by Solomyak is a powerful tool to study this problem for th
 e class of self-affine tilings. We generalize this algorithm for general $
 S$-adic tilings\, and apply it to a class of block $S$-adic tilings to sho
 w almost all of them have pure point spectra. This is a joint work with J
 örg Thuswaldner.\n
