  • 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…
  • @JohnBaez I was just thinking that a collaborative document or wiki page would make generating the list much easier!
  • 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…
