The Funayama envelope as the $T_D$-hull of a frame

Abstract

We introduce proximity morphisms between MT-algebras and show that the resulting category is equivalent to the category of frames. This is done by utilizing the Funayama envelope of a frame, which is viewed as the TDT_D-hull. Our results have some spatial ramifications, including a generalization of the TDT_D-duality of Banaschewski and Pultr.
