Title: | A combinatorial property of rho-functions | Journal: | Acta Mathematica Hungarica | Issue Date: | 5-Jul-2022 | Rank: | M22 | ISSN: | 0236-5294 | DOI: | 10.1007/s10474-022-01237-y | Abstract: | We show that if T is any Hausdorff topology on ω1, then any subset of ω1 which is homeomorphic to the rationals under T can be refined to a homeomorphic copy of the rationals on which ρ¯ is shift-increasing. |
Keywords: | partition calculus | Ramsey degree | rationals | strong coloring | Publisher: | Springer Link |
