“Chapter 19, applying these ideas ideas to study curves,…”

The second occurrence of “ideas” seems redundant.

]]>In 5.1.1, you give the definition of a quasiseparated topological space as follows: “A topological space is quasiseparated if the intersection of any two quasicompact open sets is quasicompact.”

However, Exercise 5.1F states: “Show that a scheme is quasiseparated if and only if the intersection of any two affine open subsets is a finite union of affine open subsets, if and only if the intersection of any two quasicompact open subsets is a quasicompact open subset.” It looks to me like the last if and only if is the definition of quasiseparated you give above; am I missing something?

Thanks very much for looking!
