Complement avoidance in binary words

J Currie, P Ochem, D Opočenská, N Rampersad… - arXiv preprint arXiv …, 2022 - arxiv.org
The complement $\overline {x} $ of a binary word $ x $ is obtained by changing each $0 $ in
$ x $ to $1 $ and vice versa. We study infinite binary words $\bf w $ that avoid sufficiently …

The repetition threshold for ternary rich words

JD Currie, L Mol, J Peltomäki - arXiv preprint arXiv:2409.12068, 2024 - arxiv.org
In 2014, Vesti proposed the problem of determining the repetition threshold for infinite rich
words, ie, for infinite words in which all factors of length $ n $ contain $ n $ distinct nonempty …

More characterizations of morphic words

G Badkobeh, P Ochem - arXiv preprint arXiv:2312.10757, 2023 - arxiv.org
An interesting phenomenon in combinatorics on words is when every recurrent word
satisfying some avoidance constraints has the same factor set as a morphic word. An early …
