• Not really, sorry :/ I was focusing on the more mundane question of: I have a spacecraft with a suite of instruments $$S$$ that performs a set of observations $$O$$. There is a subset of those observations that map to one of two conclusions: $${\t… • For exercise 1.83, Show that if \( f:P\rightarrow Q$$ has a a right adjoint $$g$$, then it is unique up to isomorphism. That means, for any other right adjoint $$g'$$, we have $$g(q)\cong g'(q)$$ for all $$q \in Q$$. I'm having a little trouble g…
• Pablo @ 55: is it fair to say, then, that all elements of $$A$$ must belong to a ~-connected and ~-closed subset of $$A$$? I thought of a few possible examples of posets on the train this morning, that are maybe isomorphic to the ones already descr…
• For exercise 1.12.3, I'm somewhat confused about how to go about proving this (proofs were never my strong suit). Is it not possible that $$\bigcup\limits_{p\in P} A_p = A \cap A_q$$ where $$q \notin P$$ I.e. if you union all the partitions, t…
