DESCRIPTION:Aperiodic Monotiles: New Shapes Just Dropped\n\nA longstanding
unsolved problem in geometry asks whether it is possible for a single shape
to be aperiodic: to tile the plane without ever permitting translational s
ymmetries. We recently proved that a shape called the “hat” solves this pro
blem\, making it the first known aperiodic monotile. In this talk I will in
troduce some background concepts from tiling theory and summarize the histo
ry of the search for aperiodic shapes. I will then relate the story of our
discovery of the hat and the proof of its aperiodicity. Along the way I wil
l also talk about two other closely related shapes\, the “turtle” and the “
spectre”\, which allow us to derive additional results about aperiodic tili
ngs.
