A parametric unary function $f$ of type \texttt{forall ($x_1$:$T_1$) \ldots ($x_n$:$T_n$), $A_1$ -> $A_2$} covariantly respects two parametric relation instances $R_1$ and $R_2$ if, -whenever $m, n$ satisfy $R_1~x~y$, their images $(f~x)$ and $(f~y)$ +whenever $x, y$ satisfy $R_1~x~y$, their images $(f~x)$ and $(f~y)$ satisfy $R_2~(f~x)~(f~y)$ . An $f$ that respects its input and output relations will be called a unary covariant \emph{morphism}. We can also say that $f$ is a monotone function with respect to $R_1$ and $R_2$. The sequence $x_1,\ldots x_n$ represents the parameters of the morphism. |
