Textbook or lecture notes in topological K-Theory - MathOverflow most recent 30 from http://mathoverflow.net2013-05-22T03:34:20Zhttp://mathoverflow.net/feeds/question/32198http://www.creativecommons.org/licenses/by-nc/2.5/rdfhttp://mathoverflow.net/questions/32198/textbook-or-lecture-notes-in-topological-k-theoryTextbook or lecture notes in topological K-TheoryMartin Pinsonnault2010-07-16T16:09:10Z2011-09-12T17:53:22Z
<p>I am looking for a good introductory level textbook (or set of lecture notes) on classical topological K-Theory that would be suitable for a one-semester graduate course. Ideally, it would require minimal background: standard introductory courses in algebraic topology and differential geometry, would cover core topics (Bott periodicity, Chern character, representation rings, etc) mostly in a self-contained way, and would give interesting examples and exercises. </p>
<p>As I learned the subject from multiple books and papers, I don't know a "canonical" reference that gives a coherent picture of the subject. Any suggestions ?</p>

It's called "Complex Topological K-Theory," and it is published by Cambridge University Press. As the title suggests, I do not discuss real (KO) theory in the book, and I also do not talk about representation rings. But the other topics you mentioned are covered, and the only background required for the book are introductory courses in point-set topology and abstract algebra.</p>

The Atiyah book is more readable and has fewer prerequisites,but the Karoubi book covers a great deal more. </p>

Perhaps that's because it's hard to top Atiyah & Segal's writings. Pity that Atiyah's book is so expensive. On the other hand, Segal's <a href="http://www.springerlink.com/content/p0455j88250n2424/fulltext.pdf" rel="nofollow">paper</a> on equivariant K-theory is freely available. </p>

They're from a one-semester graduate course (the second such course I've taught). Sadly, they're not yet typed...</p>
<p>They're a mix of material from Milnor and Stasheff, Hatcher's notes, and Husemoller's book Fibre Bundles. They cover vector bundles and principle bundles, characteristic classes and the Chern Character, and complex Bott periodicity. They don't cover representation rings or real K-theory. (I assume that in mentioning representation rings, you're talking about the Atiyah-Segal Theorem, or at least Atiyah's version for finite groups? I don't know any textbook reference for that.)</p>
<p>The proof of Bott periodicity that I give in the notes is a mixture of Hatcher's proof with some observations from Husemoller's book, and it uses the Chern Character to prove that the Bott map is injective. This is nice, because the proof of injectivity in Hatcher's notes (or Atiyah's book) is a bit more complicated that the proof of surjectivity. So if you're covering the Chern character anyway, this is a nice route to take.</p>

@Andrew Atiyah's book really needs some work. I don't think it is easier. </p>
