| Description: | Hrushovski showed that the theory of difference-differential fields of characteristic zero has a model-companion, which we shall denote DCFA. We give an axiomatization for DCFA and prove some important model-theoretic results as supersimplicity and elimination of imaginaries. We mention some properties of the fixed field and the constant field of a model of DCFA. |
