I had already asked a question as follows: "Is there a one dimensional foliation of a two dimensional manifold whose foliation groupoid is diffeomorphic to a 3 sphere with two north pole. The latter is constructed as follows: We take a disjoint union of two 3_ spheres S,S' and identify each point $$x$$ different from the North pole of S to the same point at S'. So we get a 3 sphere with two North poles. It is a non Hausdorff 3 manifold which is constructed in the similar way as construction of a line with 2 origin" Could you please help me to find my question. It has at least 2 tags and . I searched my questions but I did not find that question. Thank you

• I undeleted the question (the one found by Martin Sleziak). It was autodeleted, but it had no negative feedback.

• Of course, one should keep in mind that if the question still fulfills the criteria for roomba, it will be deleted the next time the script runs. (AFAICT this basically meant that t will be deleted again if it doesn't get an upvote or at least two comments.) Oct 2 at 8:38
• @StefanKohl Dear Stefan Thank you very much for undeletting my question Oct 2 at 10:41
