$Rsb{0}$-algebras, which were proved to be equivalent to Esteva and Godo's NM-algebras modelled by Fodor's nilpotent minimum t-norm, are the equivalent algebraic semantics of the left-continuous t-norm based fuzzy logic firstly introduced by Guo-jun Wang in the mid 1990s.In this paper, we first establish a Stone duality for the category of MV-skeletons of $Rsb{0}$-algebras and the category of t...

In this note we prove several duality theorems in lattice theory. We also discuss the connection between spectral spaces and Priestley spaces, and interpret Priestley duality in terms of spectral spaces. The organization of this note is as follows. In the first section we collect appropriate definitions and basic results common to many of the various topics. The next four sections consider Birk...

This is a theoretical paper giving the extended Stone duality perspective on the recently discovered connection between duality theory as studied in non-classical logic and theoretical computer science and the algebraic theory of finite state automata. As a bi-product we obtain a general result about profinite completion, namely, that it is the dual under extended Stone duality of the recognisa...

The fact that one can associate a finite monoid with universal properties to each language recognised by an automaton is central to the solution of many practical and theoretical problems in automata theory. It is particularly useful, via the advanced theory initiated by Eilenberg and Reiterman, in separating various complexity classes and, in some cases it leads to decidability of such classes...

Stone Duality

Stone-type duality connects logic, algebra, and topology in both conceptual and technical senses. This paper is intended to be a demonstration of this slogan. In this paper we focus on some versions of Fitting’s L-valued logic and L-valued modal logic for a finite distributive lattice L. Using the theory of natural dualities, we first obtain a duality for algebras of L-valued logic. Based on th...

Duality theories are proposed as a basis for the construction of certain state spaces that appear in Decision Theory. This is considered in more detail in the particular case of Stone Duality. Topological cancellation axioms for preference are introduced. These are used to produce a form of representation for preference between particular acts over state spaces that are Stone spaces. The well-k...
