Authors: | Farah, Ilijas | Title: | A coherent family of partial functions on ℕ | Journal: | Proceedings of the American Mathematical Society | Volume: | 124 | Issue: | 9 | First page: | 2845 | Last page: | 2852 | Issue Date: | 1-Jan-1996 | ISSN: | 0002-9939 | Abstract: | We prove that there is a family of partial functions fα : Aα → α (α → ω1, Aα is a tower in P(ω)/Fin) such that every surjection g : ω1 → {0, 1} is associated to a cohomologically different Hausdorff gap (see Talayco). This improves a result of Talayco. |
