A (corrected) sufficient condition for the Hausdorffness of a Reeb space
摘要
We correct a lemma on the Hausdorffness of a Reeb space from the paper “Regularity via links and Stein factorization” by Grady and Schenfisch published in this journal: we give counterexamples to that wrong lemma and formulate a correct sufficient condition for the Hausdorffness of a Reeb space.
