Modules of existentially closed algebras
Published online by Cambridge University Press: 12 March 2014
Abstract
The underlying modules of existentially closed ⊿-algebras are studied. Among other things, it is proved that they are all elementarily equivalent, and that all of them are existentially closed as modules if and only if ⊿ is regular. It is also proved that every saturated module in the appropriate elementary equivalence class underlies an ex. ⊿-algebra. Applications to some problems in module theory are given. A number of open questions are mentioned.
