Projections in a W*-algebra as a continuous lattice?
The already given answer and comments have essentially solved the problem; however I
will show the way the question can be studied from the point of view of
"classical" lattice theory (say, the times …

Can non-central projections still commute with all other projections?
[Below I consider only the unital case. I have to think about the non unital case, but it should be sufficient
to consider the associated $C^*$-algebra with unit $A\oplus K1$, with
$K$ the complex o r …
