Abstract
In earlier papers, the author studied some classes of equations with Carlitz derivatives for \(\mathbb{F}_q\)-linear functions, which are the natural function-field counterparts of linear ordinary differential equations. Here we consider equations containing self-compositions u ∘ u ... ∘ u of an unknown function. As an algebraic background, imbeddings of the composition ring of \(\mathbb{F}_q\)-linear holomorphic functions into skew fields are considered.
