Abbreviation: SdLat
A \emph{semidistributive lattice} is a lattice $\mathbf{L}=\langle L,\vee ,\wedge \rangle $ such that
SD$_{\wedge}$: $x\wedge y=x\wedge z\Longrightarrow x\wedge y=x\wedge(y\vee z)$
SD$_{\vee}$: $x\vee y=x\vee z\Longrightarrow x\vee y=x\vee(y\wedge z)$
Let $\mathbf{L}$ and $\mathbf{M}$ be semidistributive lattices. A morphism from $\mathbf{L}$ to $\mathbf{M}$ is a function $h:L\rightarrow M$ that is a homomorphism:
$h(x\vee y)=h(x)\vee h(y)$, $h(x\wedge y)=h(x)\wedge h(y)$
Example 1: $D[d]=\langle D\cup\{d'\},\vee ,\wedge\rangle$, where $D$ is any distributive lattice and $d$ is an element in it that is split into two elements $d,d'$ using Alan Day's doubling construction.
