1807. Daniel Max Hoffmann and Anand Pillay
Thorn forking, weak normality, and theories with selectors

Submission date: 28 June 2020.


We discuss the role of weakly normal formulas in the theory of thorn forking, as part of a commentary on the paper “Thorn forking and stable forking” by Ealy and Onshuus (Rev. acad. colomb. cienc. exact. fis. nat. vol.40 no.157 Bogotá Oct./Dec. 2016). We also give a counterexample to Corollary 4.2 from that paper, and in the process discuss “theories with selectors”.
