\begin{definition}
An \emph{implicative lattice} is a structure $\mathbf{A}=\langle A,\vee,\wedge,\to\rangle$ such that 

$\langle A,\vee,\wedge\rangle$ is a \href{Distributive_lattices.pdf}{distributive lattices}
$\to$ is an implication: 


$x\to(y\vee z) = (x\to y)\vee(x\to z)$


$x\to(y\wedge z) = (x\to y)\wedge(x\to z)$


$(x\vee y)\to z = (x\to z)\wedge(y\to z)$


$(x\wedge y)\to z = (x\to z)\vee(y\to z)$
\end{definition}
\begin{morphisms}
Let $\mathbf{A}$ and $\mathbf{B}$ be involutive lattices. A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a
homomorphism: 

$h(x\vee y)=h(x)\vee h(y)$, $h(x\vee y)=h(x)\wedge h(y)$, $h(x\to y)=h(x)\to h(y)$
\end{morphisms}
