Let $S$ and $T$ be classes.
A class mapping $f$ from $S$ to $T$, denoted $f: S \to T$, is a class relation $f = \mathcal R \subseteq S \times T$ such that:
- $\forall x \in S: \forall y_1, y_2 \in T: \left({x, y_1}\right) \in f \land \left({x, y_2}\right) \in f \implies y_1 = y_2$
and
- $\forall x \in S: \exists y \in T: \left({x, y}\right) \in f$
