# What happened to my question on discrete valuation rings?

I asked a question whose title was Two discrete valuation rings one of which is contained in another(Two discrete valuation rings, one contained into another). It was closed, but I have no idea why it was closed.

The quesion was: Let $A$ and $B$ be discrete valuation rings having the same field of fractions. Suppose $A \subset B$. Then $A = B$?

I wrote the motivation since some users tend to vote to close a question without it.

• At the end of you question page math.stackexchange.com/users/217571/… follow the link "deleted recent questions" you should find the question there. If you post the link to the question here you might get some more information. Without seeing the post it is hard to tell. And for everybody but you and mods it is hard to locate the question. – quid Apr 28 '15 at 0:13
• @quid Thanks for your info. – Makoto Kato Apr 28 '15 at 0:19

It had a score of $-2$, was more than 30 days old, and had no answer. Such questions are automatically deleted network wide. Your question was never closed, old negatively scored questions without activity are deleted whether closed or not. Closed questions are deleted sooner (after nine days, iirc) when they are negatively scored and have no positively scored answer.
As quid just commented, for questions not older than $60$ days, you can find these questions yourself from the "deleted recent questions" link at the bottom of the "questions" tab in your profile.
