Abstract:

For each delta operator Q, we define a multiplication of polynomials of K [ x] that makes Q a derivation in a suitable polynomial ring. We see that such derivation ring is isomorphic to K [x ] with the usual derivative operator D. We supply a complete classification of the isomorphisms between these two structures, ending with a slight generalization. Copyright 2001 Academic Press
