What properties of a C*-algebra are reflected in their $K_0$ groups? In the first two cases, the only projective modules are free, so the semi group we get is the natural numbers I know for cuntz algebras, weirder things happen when you take direct sums of projectives I would appreciate if someone could illuminate exactly what the K0 group of a C*-algebra tells us about the structure of that algebra
