Abstract
In this paper, we consider centralizers of single elements in certain
Ore extensions, with a non-invertible endomorphism, of the ring of polynomials
in one variable over a field. We show that they are commutative and finitely
generated as algebras. We also show that for certain classes of elements their
centralizer is singly generated as an algebra.
