Research Abstract

With Jeong-Yup Lee we developed a practical algorithm to check pure discreteness of translation dynamics of the orbit closure of self-affine tilings with Pisot family condition. Pisot numbers often appears as dilation constants of self-inducing structures. We observed similar Pisot dilations in the self-similar dissection problem of planar shapes in the joint paper with R. Okazaki, J. Luo, J. Thuswaldner and W. Steiner. With Benoit Loridant, we succeeded in giving a standard parameterization of boundaries of self-affine tilings and showed its effectiveness in their topological classification.
