Differential fields Differential fields are fields equipped with a derivation, i.e., allow to take derivatives of elements in the field. For example, the field , together with the standard derivative of polynomials forms a differential field. These fields are central to differential Galois theory, a variant of Galois theory dealing with linear differential equations.
