The continuous weak order
Maria João Gouveia, Luigi Santocanale
The set of permutations on a finite set can be given the lattice structure known as the weak Bruhat order. This lattice structure is generalized to the set of words on a fixed alph…
Mix -autonomous quantales and the continuous weak order
Maria João Gouveia, Luigi Santocanale
The set of permutations on a finite set can be given a lattice structure (known as the weak Bruhat order). The lattice structure is generalized to the set of words on a fixed alpha…
Ruitenburg's Theorem via Duality and Bounded Bisimulations
Luigi Santocanale, Silvio Ghilardi
For a given intuitionistic propositional formula A and a propositional variable x occurring in it, define the infinite sequence of formulae { A \_i | i1} by letting A\_1 be A…
Fixed-point elimination in the Intuitionistic Propositional Calculus (extended version)
Silvio Ghilardi, Maria Joao Gouveia, Luigi Santocanale
It is a consequence of existing literature that least and greatest fixed-points of monotone polynomials on Heyting algebras-that is, the alge- braic models of the Intuitionistic Pr…
