LetRbe a ring. We prove that the homotopy categoryK(R-Proj) is always-compactly generated, and, depending on the ringR, it may or may not be compactly generated. We use this to give a description ofK(R-Proj) as a quotient ofK(R-Flat). The remarkable fact is that this new description ofK(R-Proj) generalizes to non-affine schemes; this will appear in Murfet’s thesis.
