Real Analysis 2018-19

Spring 2019: MWF, 10:10-11:00, Vincent 206. Text will be notes posted here, supplemented by any standard text or notes that suit your taste.

Prerequisites for 8601: strong understanding of a year of undergrad real analysis, such as our 5615H-5616H or equivalent, including careful discussion of Riemann integration on Euclidean spaces, the basic topology of Euclidean spaces, and abstract metric spaces. Prerequisites for 8602: 8601 or equivalent.

Sources: The measure-and-integration we will cover is standard, and can be found in many sources, in addition to the write-ups here. Similarly, basics about Hilbert spaces and Banach spaces can be found in many places. The notes that will appear here will de-emphasize pathologies (except as cautionary tales). Looking at a variety of sources is recommended, as a way to avoid getting caught up in the idiosyncrasies of any particular source. At the same time, many of these sources are ridiculously expensive... Also, many have not been updated to reflect progress in mathematics over the last 80+ years! Although measure-and-integration succeeded in addressing certain issures, it by far did not completely succeed, and a good part of the progress in analysis 1915-2015 aims at greater success than measure-and-integration alone can achieve.

Spring grades will be determined by three in-class midterms , scheduled as in the table below. You are not competing against other students in the course, and I will not post grade distributions. Rather, the grade regimes are roughly 90-100 = A, 75-90 = B, 65-75 = C, etc., with finer gradations of pluses and minuses. So it is possible that everyone gets a "A", or oppositely. That is, there are concrete goals, determined by what essentially all mathematicians need to know, and would be happy to know.

In Spring 2019, classes end Monday, May 6, 2019.

There will be regular homework assignments preparatory to exams, on which I'll give you feedback about mathematical content and writing style. The homeworks will not directly contribute to the course grade, and in principle are optional, but it would probably be unwise not to do them and get feedback. No late homeworks will be accepted. Homework should be typeset, presumably via (La)TeX.

Office hours: MWF 11:15-12:20. Send email anytime!

Cumulative notes are or will be also grouped into an evolving single PDF. There is a Fall 2017 version already available.

Partial outline: ... resembling last year's...
