Intersession homework: read chapters 7 and 8. These chapters will be covered rapidly at the beginning of MAT 550.
Section 6.3, the "Suggested Intersession Reading" in chapter 6 and the "Postponed Proofs" sections in Chapters 7 and 8 are optional reading (you are not going to be tested on them, but they are HIGHLY RECOMMENDED).
Before leaving for intersession, please go to the math library, and make a copy of Doss's one-page proof of the Hahn Decomposition Theorem, in the Proceedings of the American Mathematical Society, of October 1980; you will want to have this when reading chapter 8.
