Here, completely getting rid of that useless weird = sign, are
much better, clearer and direct statements of the definitions.

A thorning of a point a in a complete lattice L
is a subset A, of L\bottom with sup S = a and
bottom /= x inf y

A weak partition of an element a in a complete lattice L
is a subset A, of L\bottom with sup A = a and for all
x in A, bottom /= a inf (sup A\x)

A strong partition of an element a in a complete lattice L
is a subset A, of L\bottom with sup A = a and for all
U,V subset A, (U /\ V not empty iff bottom /= (sup U) inf (sup V))

A strong partition of an element a in a complete lattice L
is a subset A, of L\bottom with sup A = a and for all
U,V subset A, (U /\ V empty iff bottom = (sup U) inf (sup V))
