| Sep 13, 2011 at 14:55 | comment | added | Mohammad Farajzadeh-Tehrani | Yes, simple, I mean some thing you can check when you have the local analytic defining equations of the map $f$. the standard definition is in terms of flat modules and local rings. But I am not so comfortable with local rings ... . May be some explicit example can help me learn how to deal with a given equation. The easiest one is $ f: \mathbb{C}^2 \rightarrow \mathbb{C}$ given by $(x,y)\rightarrow xy$. How do you check the flatness for this one at origin? | |
