Added that X is supposed to be Hausdorff. See the comments according to the answer.

| May 2, 2012 at 4:45 | comment | added | Ali Reza | Yes Dear Ralph. i am sorry about my wrong notation. I should write: $Z(I)=\lbrace Z(f): f \in I\rbrace$ | |
| May 2, 2012 at 0:22 | comment | added | Ralph | Shouldn't it be $Z(I)=\lbrace Z(f): f \in I\rbrace$ (instead of $f \in C(X)$) ? | |
| May 1, 2012 at 20:56 | comment | added | Ali Reza | Dear Matthew $Z(I):=${$Z(f):f\inC(X)$} i.e. every element of $Z(I)$ is a set of the form $Z(f)$ that $f$ belongs to the ideal $I$. Thank you for your comment | |
| May 1, 2012 at 20:38 | comment | added | Matthew Daws | Is actually $Z[I]$ equal to the intersection of all the sets $Z[f]$ with $f\in I$? | |

| Apr 30, 2012 at 12:26 | comment | added | David White | I've noticed you are asking a lot of questions and they are not getting much attention. There are several reasons. First, you should define $Z(f)$ in each one, since this is not standard notation. Also, you should use dollar signs to make the mathematics appear as mathematics. It wouldn't hurt to give more background, like what you have tried on the problem and why you care about the answer. Have you read the "How to Ask" page yet? Have you thought about asking on math.stackexchange? Spending time there for a while learning how to ask would not hurt you. | |
