The standard eBook edition comes as personalized
high-quality PDF that can be read on any computer or tablet. There is no opening password.
The cross-references in the text are active links: when a proof cites
"Lemma 3.1", for example, click on the "3.1" to be taken to that
lemma. For each result or proof, there are links in the margin to
take you to the results needed for this proof, or in whose proof the
current result is used.
The price for the eBook edition is the same in all three formats –
Standard eBook, iBook, and iOS app.
