Chair Tiling
This animation shows the tiling substitution producing the “chair” tiling. It is an example of a constant “size” substitution with a “coincidence”. As a result this tiling has discrete diffraction spectrum. See the paper “On the table and the chair” Indag. Math 10, 1999.
Research
✴ Ergodic theory and dynamical systems, (applications to tilings, quasicrystals, and numeration). See my papers and old lectures.
✴ Applications of mathematics to politics. My book (right) coauthored with Dan Ullman.
* Visual Mathematics (Math and Art). Digital media, 3d printing, laser cutting.
