May 10, 2013 at 23:11 | comment | added | Ramiro de la Vega | @Goldstern: Thats's right, my comment about well-met posets was answering a question made by Butch in another comment not the original question. Sorry for the confusion. | |
May 10, 2013 at 22:03 | comment | added | Goldstern | @ramiro: I think that a forcing notion is called "well-met" if any two conditions with a common lower bound have a greatest lower bound. This is slightly stronger than "DUB". jstor.org/stable/2274204 | |

May 10, 2013 at 0:03 | comment | added | Asaf Karagila♦ | What does it mean that $\lbrace a,b\rbrace\leq\lbrace c,d\rbrace$? Both $a$ and $b$ are smaller than both $c$ and $d$? | |
May 9, 2013 at 23:33 | comment | added | Joel David Hamkins | In analogy with the LUB property, you could call it the DUB property (directed upper bound property), since you are saying that every bounded-above finite set has a directed collection of upper bounds (and similarly for lower bounds). | |
May 9, 2013 at 22:50 | comment | added | Ramiro de la Vega | That´s sometimes called a well-joined (well-met for the dual notion) partial order. | |
May 9, 2013 at 22:16 | comment | added | Ramiro de la Vega | Trees also have this property. | |
