Theoretical Foundations of Computer Science
On safety of recursive queries
S. M. Dudakov Tver State University, Tver
Abstract:
We investigate a totality of recursive queries on infinite universes. A recursive query model, which is considered, is inflationary fix point $IFP$. Properties of $IFP$-operator are investigated. We prove that models of countable categorical theories are safe.
Keywords:
inflationary fix point, countable categoricity.
