Topology of some tiling spaces without finite local complexity
A basic assumption of tiling theory is that adjacent tiles can meet
in only a finite number of ways, up to rigid motions. However,
there are many interesting tiling spaces that do not have this
property. They have "fault lines", along which tiles can slide
past one another. We investigate the topology of a certain class of
tiling spaces of this type. We show that they can be written as
inverse limits of CW complexes, and their Čech cohomology is
related to properties of the fault lines.
