I have run a [SEDE](https://meta.mathoverflow.net/tags/data-explorer/info) query to list your questions: [Questions (id, title) of a given user
](https://data.stackexchange.com/mathoverflow/revision/1013692/1252372/questions-id-title-of-a-given-user). Since SEDE is updated once a week (you can see "Data updated Mar 17 at 8:47" in the [Data Explorer](https://data.stackexchange.com/), these data still contain the posts which were posted before last week - even if they were deleted during this week.

You could download the query results after the update and compare the two files. However, I tried to check this manually and compare the list from SEDE with the list of questions in your profile. I found three following questions which seemed to be deleted at the moment.

 * [A length decreasing homotopy of a closed curve in a simply connected manifold](https://mathoverflow.net/questions/285866/a-length-decreasing-homotopy-of-a-closed-curve-in-a-simply-connected-manifold) ([Google Cache](https://webcache.googleusercontent.com/search?q=cache:https://mathoverflow.net/questions/285866/a-length-decreasing-homotopy-of-a-closed-curve-in-a-simply-connected-manifold))
 * [An explicit formula for a flat metric compatible to certain polynomial vector field with center](https://mathoverflow.net/questions/272768/a-differential-operator-associated-with-a-vector-field-on-the-torus) ([Google Cache](https://webcache.googleusercontent.com/search?q=cache:https://mathoverflow.net/questions/272768/a-differential-operator-associated-with-a-vector-field-on-the-torus))
 * [Integrability of distributions which are invariant under the isometry group](https://mathoverflow.net/questions/264043/integrability-of-distributions-which-are-invariant-under-the-isometry-group) ([Google Cache](https://webcache.googleusercontent.com/search?q=cache:https://mathoverflow.net/questions/264043/integrability-of-distributions-which-are-invariant-under-the-isometry-group))

Since you are the poster of those question, now that you have links you should be able to access them. 

I have checked whether they are available in [Internet Archive](https://en.wikipedia.org/wiki/Internet_Archive), but I did not find any of these three questions there. As you can see, at the moment some version of the post is also available through Google cache (links are given above) - but I suppose that those cached links will stop working at some point.
