Verification of Data-Aware Processes via Array-Based Systems (Extended Version)
Diego Calvanese, Silvio Ghilardi, Alessandro Gianola +2
We study verification over a general model of artifact-centric systems, to assess (parameterized) safety properties irrespectively of the initial database instance. We view such ar…
Quantifier Elimination for Database Driven Verification
Diego Calvanese, Silvio Ghilardi, Alessandro Gianola +2
Running verification tasks in database driven systems requires solving quantifier elimination problems of a new kind. These quantifier elimination problems are related to the notio…
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…
