One-element $p$-bases of rings of constants of derivations

Piotr Jędrzejewicz
In this paper we present sufficient conditions and necessary conditions for a single element to form a p-basis of a ring of constants of a derivation. We consider some special cases, when these conditions are equivalent, and we analyze some counter-examples, when the equivalence does not hold.
