Summary: A NOTE ON APERIODIC AMMANN TILES
SHIGEKI AKIYAMA
Abstract. We present a variant of Ammann tiles consisting of two
similar rectilinear hexagons with edge subdivision, which can tile the
plane but only in non periodic ways. A special matching rule, ghost
marking, plays a key role in the proof.
We shall show that the set of tiles in Figure 1 is aperiodic, that is, it tiles
the plane but only in non periodic way.
