A virtually nilpotent group with non D-finite Green series
Published 20 Sep 2024 in math.GR, math.CO, and math.NT | (2409.13395v1)
Abstract: We provide an example of a virtually $2$-step nilpotent group, and a specific generating set, for which the Green series (sometimes called cogrowth series) is not D-finite. The proof relies on an arithmetical miracle, and the study of the subword complexity of a multiplicative sequence coming out of it.
