Aug 4, 2011 at 15:31 | comment | added | Mahdi Majidi-Zolbanin | I just found out that in SGA 1 (arxiv.org/abs/math/0206203) Grothendieck calls such maps quasi-finite (see pages 1 and 2 of SGA 1). | |
Aug 1, 2011 at 19:10 | comment | added | Mahdi Majidi-Zolbanin | @David: For example, if $R$ is a Noetherian local ring of characteristic $p>0$ and its residue field $k$ satisfies $[k:k^p]<\infty$, then the Frobenius endomorphism $\varphi:R\rightarrow R$ may not be a finite map, but $\hat{\varphi}:\hat{R}\rightarrow\hat{R}$ will be a finite map. | |
Aug 1, 2011 at 19:03 | comment | added | Mahdi Majidi-Zolbanin | I'll be happy to use analytically finite, if there is no name for this. | |

Jul 30, 2011 at 14:35 | comment | added | the L | Actually, there is a notion of a formally finite map: A map between two adic rings $(A,\mathfrak{a}) \to (B,\mathfrak{b})$ is called formally finite if $B/\mathfrak{b}$ is a finite $A$-module. | |
Jul 30, 2011 at 14:19 | comment | added | David White | I figured I'd tag as algebraic geometry since there is probably a nice geometric way to understand such maps and they may have a term for them. I've never come across anything with this description personally, but I'm not an algebraic geometer | |
