A ring $A$ with one or more distinguished derivations (cf. [[Derivation in a ring]]). An element $a \in A$ such that $d(a) = 0$ for all these derivations $d$ is said to be a ''constant''.  The constants form a subring of $A$.

A ring $A$ with one or more distinguished derivations (cf. Derivation in a ring). An element $a \in A$ such that $d(a) = 0$ for all these derivations $d$ is said to be a constant. The constants form a subring of $A$.
