題名 : Commutative algebra over valuation rings
要旨 : We discuss some recent and forthcoming work on finitely presented algebras over valuation rings. Specifically, we will discuss properties around regularity and dualizing complexes. We will also explain how Noetherian approximation is used to generalize known results for Noetherian rings to our setup. At the end, we will give applications of our result back to Noetherian rings (e.g. over Z_p).
