So I went back to the book store³ and went through all of their books⁴. I couldn’t order Measure and Integral by Wheeden because it was just too expensive for my taste. Instead, I bought Principles of Real Analysis by Charalambos Aliprantis. I paid $30 for the hardcover 3rd edition, which is out of print because it’s listed on Amazon for $140. I wouldn’t mind getting the companion problem book as well. The Principles book was a third of the price of Measure. I’ve decided to get a photocopied version of that book. Since I was there, I ordered Real and Complex Analysis by Walter Rudin, a steal at only $15.
While browsing through the aisles, I saw Probability Theory I and II by M. Loève. Both were original hardcover editions that cost me $6.18 each. In the US, you’d bay between $70-90 for each volume. They are vol 45 and 46 in Springer-Verlag’s Graduate Texts in Mathematics. I found a few cheap undergraduate texts as well. Serge Lang’s Calculus of Several Variables, hardcover 3rd edition, David Bressoud’s Second Year Calculus, and Murray Protter’s Basic Elements of Real Analysis. They cost me respectively $9, $6.18, and $6.18.
I was really intrigued by Lie Algebras and their Applications by Francesco Iachello but I balked at the price for such a thin volume¹. Laplacian Eigenvectors of Graphs: Perron-Frobenius and Faber-Krahn Type Theorems by Türker Biyikoglu, Josef Leydold, Peter F. Stadler in the Lecture Notes in Mathematics series at Springer was also really interesting, but way too expensive to splurge on².
I went through all of the Springer Verlag math books, as they were easy to spot. I tried finding a good text on Algebra, but I think that the volume I ordered, namely Hungerford’s Algebra, will deal with all of my questions. The was a book on Field and Galois Theory by Howie, but it was thin, softcover and a bit too expensive for now.
I’ve bought about 11 textbooks in the last three days, for about $120. That’s more than books than I have ever bought before. In the past, I rarely bought the books. If I bought any, it was only because they were required for classes.

[¹]: It’s a 197-page hardcover that deals with the applications of lie algebras in physics. It cost $57 and they had quite a few copies. I asked if they were going to go on special. They rudely replied no. That’s too bad.
[²]: Price was about $40 for 120 pages. It was a softcover book.
[³]: Einstein book store, located right on top of the McDonalds in front of Taida near Gongguan MRT, 02-2363-5233, 新生南路三號88號2樓之1, Xinsheng South Road, Section 3, #88, 2F, Suite 1.
[⁴]: That’s actually untrue. I went through all of their Springer Verlag books. I didn’t even go through all of the math books. That would take about an hour or so. The books would have to be taken out and checked individually. Sure, I guess I could always use the website.
