Tiling semigroups were first considered by J. Kellendonk and M. Lawson following the work of Kellendonk regarding the modelling of solids using gap labelling.
In this talk, we will give a presentation for the inverse semigroup associated with a factorial language, which is a generalization of the tiling semigroup of a onedimensional tiling, and discuss some conditions on the tiling in order for the presentation to be finite.
This is a joint work with D. B. McAlister.
