But to make up for it here are some comments: 1. the definition of $K(C)$ is a slight variation of the definition of the motivic measure, which in turn goes back to other similar definitions (e.g. the Grothendieck group for coherent sheaves etc) 2. the Borel-Moore homology of a space $X$ (with constant coefficients) is the homology of the one point compactification modulo the added point. | |
