TL;DR: In this paper, the basic notions of quantales and quantale modules are introduced and a survey of the recent developments involving representations and projectivity in quantales is given. But quantales do not form a variety but many of the methods of universal algebra can still be still used.
Abstract: Publisher Summary This chapter introduces the basic notions in theory of quantales. It describes the aspects of algebraic and categorical properties of quantales and quantale modules. This chapter also summarizes the recent developments involving representations and projectivity in quantales. Because of infinitesimal joins, quantales do not form a variety but many of the methods of universal algebra can be still used. Quantales are also applied in linear and other substructural logics and automaton theory. An important moment in the development of the theory of quantales was the realization that quantales give the semantics for propositional linear logic in the same way as Boolean algebras give semantics for classical propositional logic.
TL;DR: In this paper, the problem of defining the concept of point of the spectrum of a -algebra A, which is one of the motivating examples of a Gelfand quantale, is considered.
TL;DR: In this article, a systematic investigation of completeness and directed completeness of @W-categories is presented, based on the theory of @F-completeness for enriched categories.
TL;DR: This paper introduces a new approach to the theory of Ω-categories enriched by a frame and introduces concepts of adjoints and a kind of convergence in an L-Fuzzy poset that makes the theory “constructive” or “computable”.
