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.
