| Oct 24, 2013 at 13:59 | comment | added | Johannes Hahn | There are a lot of "suppose" here... The reverse of an order is always an order, so you don't have to suppose that $\overline{P}$ is a poset, that's always true. Along the same lines: The chains of $P$ are the same as the chains in $\overline{P}$ so again the assumption that $\overline{P}$ has finite chains is not really an assumption, it's always true. And then we arrive at what @BorisNovikov said: Since the chains are the same, the complexes are the same (as simplicial complexes not just homemorphic). What was the question again? | |
