Definition:Right Operation

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 $S \times S$:

$\forall \tuple {x, y} \in S \times S: \pr_2 \tuple {x, y} = y$
