Abstract

In his PhD Thesis, Johan Lindberg gave an explicit description of the Joyal-Tierney representation theorem in terms of locales of models of geometric theories. We revisit this description and show an example application of it by giving a constructive formulation and proof of the Definability Theorem for coherent logic (Elephant, D3.5.1).
