Abbreviation: SkLat
A \emph{skew lattice} is a structure A=⟨A,∨,∧⟩, of type ⟨2,2⟩ such that
⟨A,∨⟩ is a band,
⟨A,∧⟩ is a band,
and the following absorption laws hold: x∧(x∨y)=x=x∨(x∧y), (x∨y)∧y=y=(x∧y)∨y.
Let A and B be skew lattices. A morphism from A to B is a function h:A→B that is a homomorphism: h(x∨y)=h(x)∨h(y), h(x∧y)=h(x)∧h(y),
