要約
Summary:
First the idea of an "inflation-species" of
tilings will be explained and some basic notions and
facts will be discussed. Further a number of examples
with rather striking properties will be presented, among
them a so-called "EINSTEIN". The latter
species cannot be defined by inflation,
but instead has a simple local matching rule.
