Issue Date: | Aug-2006 | Citation: | Downey, R., Yu, L. (2006-08). Arithmetical sacks forcing. Archive for Mathematical Logic 45 (6) : 715-720. ScholarBank@NUS Repository. https://doi.org/10.1007/s00153-006-0004-4 | Abstract: | We answer a question of Jockusch by constructing a hyperimmune-free minimal degree below a 1-generic one. To do this we introduce a new forcing notion called arithmetical Sacks forcing. Some other applications are presented. | Source Title: | Archive for Mathematical Logic | URI: | http://scholarbank.nus.edu.sg/handle/10635/102882 | ISSN: | 09335846 | DOI: | 10.1007/s00153-006-0004-4 |
