Inflated

Adic Topology and Completionrature and complete the picture with some new observations. A few of these facts hold in full generality; but most of them require that the adic topology is taken with respect to a finitely generated ideal. The case when the ring is Noetherian is easier to handle, though far from being obvious when

Dualizing Complexeser. Most of the results are not new, but some proofs are. In particular, we provide a proof of the existence of a dualizing complex for a complete Noetherian local ring independent of the Cohen structure theorem. This is part of an interesting interaction between the notion of a dualizing complex fo
