McKinsey-Tarski algebras and Raney extensions

Guram Bezhanishvili, Ranjitha Raviprakash, Anna Laura Suarez +1

We introduce the notion of Raney morphism between MT-algebras and show that the resulting category is equivalent to the category of Raney extensions. This is done by generalizing t…

The Funayama envelope as the -hull of a frame

Guram Bezhanishvili, Ranjitha Raviprakash, Anna Laura Suarez +1

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 o…
