Abstract
Elements of Thompsons group F can be defined as an affine interpolation of regular subdivisions of the unit interval. We define regular subdivisions associated with subdivision polynomials and determine which regular subdivisions can be used to create the elements of the groups FĪ with Ī an algebraic integer. By adapting the work of S. Cleary and J. Brown, we find that for degree 2, the subdivision polynomials must be Pisot polynomials.
