I am just a man who has an insatiable desire for knowledge.

"For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."~ Philippians 4:8

Nov 18	comment	Answering Questions For A Poset. To answer your question, "Can you figure out what these definitions tell you in terms of your given relation?": If $a$ and $b$ are in the poset, and $a\|b$, then $a$ precedes $b$; but if $a$ is a multiple of $b$, then b precedes a. "Note what this entails in terms of comparability." x can only be a maximal with respect to the elements it is comparable to? Similarly, x can only be a minimal with respect to the elements it is comparable to?
Nov 18	comment	Answering Questions For A Poset. @DonAntonio What do you mean? It didn't ask me to write the order.
Nov 18	comment	Answering Questions For A Poset. @DonAntonio The order on the relation is divisibility $\|$.

Nov 17	comment	Reflexive Transitive Closure Is it possible for you to provide me with a definition that hints at these things? The definition my book provides doesn't even remotely suggest that a covering relation can't be reflexive--actually, my book does not really have nice succinct definition on this concept.
Nov 17	comment	Reflexive Transitive Closure @BrianScott Why isn't a covering relation generally transitive; why isn't it ever reflexive?
Nov 17	comment	Reflexive Transitive Closure What do you mean by this, "If $R$ is already reflexive and transitive, then $R$ is its own reflexive transitive closure, but that’s not the case with your covering relations." A covering relation isn't transitive or reflexive?

Nov 16	comment	Establishing A Covering Relation No, I mean, why can't it be that $(\{a,b\},\{a,b,c\}$ is not in the covering relation, and $(\{a\},\{a,b,c\}$ is?
Nov 16	comment	Establishing A Covering Relation Also, the answer key says that $(\{a\},\{a,b,c\}$ won't be in there, but $(\{a,b\},\{a,b,c\}$. Why couldn't it be the other way around?

Nov 16	comment	Establishing A Covering Relation @ThomasAndrews My question is, why does it have to be a proper subset? I edited my post to include the description my book gives on Covering relations.
