Jul 21, 2012 at 16:34 comment added JHM You should clarify your definition of $L(X)$. ie. does it consist of those $y\in N$ for which $X\times \{y\} \subset L$ or just those $y$ for which there exists an $x\in X$ such that $(x,y) \in L$ ? And does ''correspondence'' just mean $L$ is a subset of $M \times N$ or something more?
