WebC(X) is related to algebraic K-theory via Waldhausen’s ‘algebraic K-theory of topo-logical spaces’ functor A(X). Special case with an easy deﬁnition: Let G(∨kS n) be the monoid of basepoint-preserving homotopy equivalences ∨kS n→∨ k S n. Stabilize this by letting k and n go to in-ﬁnity, producing a monoid G(∨∞S ∞). Then ... Web13. I am interesting in learning about (topological) K-theory. As far as I can see there are 3 main references used: 1) Atiyah's book: This looks to be very readable and requires minimal pre-requesities. However, the big downside is there are no exercises. 2) Allan Hatcher's online notes: If his Algebraic Topology book is any guide, this should ...

Web16. Reduced K -groups are ideals of the standard K -groups. K ~ ( X) ⊂ K ( X) is the ideal of virtual-dimension-zero elements. In particular, the reduced K-theory K ~ ( S 2) is not Z [ H] / ( H − 1) 2, but rather the ideal of this generated by ( H − 1). In particular, any element in this group does square to zero. WebFundamental to K-theory is the association of a pair of Abelian groups, K0(A) and K1(A), to each C*-algebra A. These groups reflect the properties of A in many ways.
