On the modulus of continuity for spectral measures in substitution dynamics (2013, background): “The reader is referred to [34, 20] for the background on substitutions and substitution dynamical systems.”
Beyond Sturmian sequences: coding linear trajectories in the regular octagon (2011, background): “They have been characterized as the non-periodic sequences of minimal complexity (see [7]) and have been considered by many authors since then (see [1] for a contemporary account and [14] for a historical survey).”
Topological Properties of Rauzy Fractals (2010, background): “Naturally, their symbolic dynamical systems are generated by substitutions [66, 108].”
Geometric theory of unimodular Pisot substitutions (2006, background): “Also, in [11], unique ergodicity of the shift map on the substitutive system associated with φ is shown.”
Beyond substitutive dynamical systems: S-adic expansions (2013, background): “Note that the notion of substitution occurs in various fields of mathematics (symbolic dynamics, ergodic theory, number theory, harmonic analysis, fractal theory), as well as in theoretical computer science (combinatorics on words and language theory), physics (quasicrystalline structures), and even”
Sturmian and episturmian words: a survey of some recent results (2007, background): “For a systematic exposition, see [32] and [33].”
