Talk:Complemented lattice

Uniquely complemented but not orthocomplemented?

I wonder if the obvious involution in a uniquely complemented lattice is an orthocomplementation. --Hans Adler (talk) 15:11, 7 February 2008 (UTC)[reply]

Complemented Distributed Lattice

"In distributive lattices, complements are unique." Add if they exist

Not all distributive lattices have a complement for every element. And not all complemented lattices are distributive. So the next sentence should make it clear:

"Every complemented distributive lattice ..." is talking about a subset of complemented lattices and a subset of distributive lattices. This map shows it clearly.
