From: [Permission pending] Subject: K theory To: rusin@math.niu.edu Date: Tue, 8 Apr 1997 20:18:32 +0300 (IDT) [deletia -- djr] Your web including answers to questions in topology was very interesting and I wondered whether I could ask you my own question. I am trying to find some text with examples how to compute the K theory groups of some basic spaces such as S1, S2, the torus and so on. I am not talking about heavy theorems, but about simple computations which are missing in the classical books on this subject (Atiah, Karuby) Can you give me a reference to some text on this material?

Look up "clutching functions" and the Bott periodicity theorem in the index. The conclusion is (as I recall) K(S^n)=Z+Z or Z according as n is even or odd. Another source might be Husemoller's book on Fibre Bundles. dave
