Abstract
Abstract We discuss the role of weakly normal formulas in the theory of thorn forking, as part of a commentary on the paper [5]. We also give a counterexample to Corollary 4.2 from that paper, and in the process discuss “theories with selectors.”
期刊介绍：
The Journal of Symbolic Logic publishes research in mathematical logic and its applications of the highest quality. Papers are expected to exhibit innovation and not merely be minor variations on established work. They should also be of interest to a broad audience. JSL has been, since its establishment in 1936, the leading journal in the world devoted to mathematical logic. Its prestige derives from its longevity and from the standard of submissions -- which, combined with the standards of reviewing, all contribute to the fact that it receives more citations than any other journal in logic.
