Combined Covers and Beth Definability (Extended Version)
Diego Calvanese, Silvio Ghilardi, Alessandro Gianola +2
In ESOP 2008, Gulwani and Musuvathi introduced a notion of cover and exploited it to handle infinite-state model checking problems. Motivated by applications to the verification of…
Formal Modeling and SMT-Based Parameterized Verification of Data-Aware BPMN (Extended Version)
Diego Calvanese, Silvio Ghilardi, Alessandro Gianola +2
We propose DAB -- a data-aware extension of BPMN where the process operates over case and persistent data (partitioned into a read-only database called catalog and a read-write dat…
Formal Modeling and SMT-Based Parameterized Verification of Multi-Case Data-Aware BPMN
Diego Calvanese, Silvio Ghilardi, Alessandro Gianola +2
We propose DAB -- a data-aware extension of the BPMN de-facto standard with the ability of operating over case and persistent data (partitioned into a read-only catalog and a read-…
Free Heyting Algebra Endomorphisms: Ruitenburg's Theorem and Beyond
Silvio Ghilardi, Luigi Santocanale
Ruitenburg's Theorem says that every endomorphism f of a finitely generated free Heyting algebra is ultimately periodic if f fixes all the generators but one. More precisely, there…
