Existence of an infinite word with a rauzy graph sequence that contains a subsequence of homeomorphs of graphs of the given sequence

Abstract:
We investigate infinite words on a finite alphabet and prove that for any sequence of strongly connected directed graphs with maximal in and out vertices degrees that are equal to $s$ there exists a uniformly recurrent infinite word on a $s$-letters alphabet with a Rauzy graph sequence that contains a subsequence of homeomorphs of graphs of the given sequence.
