Repetitivity of semigroups and a result of Cassaigne, Currie, Schaeffer and Shallit

ABSTRACT
The recent remarkable result of Cassaigne et al. about existence of an infinite word without three consecutive factors ‘of the same sum and size’ let appear the importance of the theory of ‘repetitive semigroups’ in that problematics. This seems an occasion to recall the main definitions and results in the theory of repetitivity, which had been shortly presented in the first Lothaire book. We recall the progresses since this epoch and in the last section formulate the results.
