Issue Date: | Dec-2006 | Citation: | Yang, Y., Yu, L. (2006-12). On Σ1-structural differences among finite levels of the Ershov hierarchy. Journal of Symbolic Logic 71 (4) : 1223-1236. ScholarBank@NUS Repository. https://doi.org/10.2178/jsl/1164060453 | Abstract: | We show that the structure ℛ of recursively enumerable degrees is not a Σ1-elementary substructure of script Dn, where script Dn (n > 1) is the structure of n-r.e. degrees in the Ershov hierarchy. © 2006, Association for Symbolic Logic. | Source Title: | Journal of Symbolic Logic | URI: | http://scholarbank.nus.edu.sg/handle/10635/103858 | ISSN: | 00224812 | DOI: | 10.2178/jsl/1164060453 |
