The tutorial emphasizes techniques rather than abstract theory. However, the conditions under which each technique is applicable are stated precisely; a guiding principle is “accessible precision”.
I try to include only the minimal assumptions needed for each result, although I deviate from this principle when the weakest possible assumptions are complicated. For each result, I give either a proof or a reference to a proof. Proofs that are visible by default (when a page is loaded) are at the same level as the tutorial; if you understand the results, you should be able to understand those proofs. Proofs that are hidden by default (i.e. are visible only after you click a button) are at a higher level. They are still self-contained, but are mathematically more sophisticated than the material that is visible by default.
All pages are intended to look good on a screen of any size. If a page does not look good on your device, let me know (by clicking the link at the bottom of any page).

AcknowledgmentsI am grateful to Kim Border for setting me straight on several points. I have benefitted a lot from his “notes” on various mathematical topics. (They are pitched at a much higher level than this tutorial.) I am grateful also to John Burbidge and Omar Sherif Elwakil, both of whom provided detailed comments on the entire tutorial.
I thank also the many readers who have pointed out errors and suggested improvements. Regrettably, until February 2014 I failed to carefully keep track of everyone who has done so. The following list includes everyone who has contributed since February 2014, together with those who contributed earlier and left evidence in my email records: Metin Akyol, Chetali Arora, Zishan Bhatti, Brandyn Bok, Vadim Borokhov, Charles Bowyer, Bogdan Budescu, John Burbidge, Domenico D'Amico, Amal Desai, Jon Duan, Juan Andres Espinosa Torres, Devrup Ghatak, Odd Godal, Ujo Goto, Jack Gregory, Tim Heilman, Ibrahim Inal, Mahsa Khoshnama, Ananya Kotia, Nicolas Lepage-Saucier, Alice Lépissier, Chester Madrazo, Francis McDonnell, Wilfred Ngia, Amol Singh Raswan, Shreya Tayal, Scott Tennican, Anjalee Sandrasegaran, Ian Siqueira, Ruolong Xiao, Xiaoyuan Yao, and Siqi Esmeralda Wu.
I am very grateful to Alejandro Lynch for generous technical advice.
