Definition:Right Operation
From ProofWiki
Definition
Let $S$ be a set.
For any $x, y \in S$, the right operation on $S$ is the binary operation defined as:
- $\forall x, y \in S: x \rightarrow y = y$
It is clear that the right operation is the same thing as the second projection on $S \times S$:
- $\forall \left({x, y}\right) \in S \times S: \operatorname{pr}_2 \left({x, y}\right) = y$
