2020 Mathematics Subject Classification: Primary: 16W25 [MSN][ZBL]
A ring 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 differential field is a differential ring that is a field. The set of constants of a differential field is a subfield, the so-called field of constants.
