Derivations in Univariate Polynomial Subalgebras of Finite Codimension
In this text we continue the work of describing subalgebras of K[x] of finite codimension that was started in “Describing subalgebras of K[x] using derivatives” [2]. In the referenced paper, the authors present how such subalgebras can be described by conditions on the values in certain points and proceed to develop a large theoretical framework to under-stand the nature of such conditions.
