Abstract. Proofs in Ludics, have an interpretation provided by their counter-proofs, that is the objects they interact with. We shall follow the same idea by proposing that sentenc...
We investigate the connection between propositional proof systems and their canonical pairs. It is known that simulations between proof systems translate to reductions between the...
The Helly number of a family of sets with empty intersection is the size of its largest inclusionwise minimal sub-family with empty intersection. Let F be a finite family of open...
Several proof systems allow the formal verification of Java programs, and a specification language was specifically designed for Java. However, none of these systems support generi...
Security policies are abstract descriptions of how a system should behave to be secure. They typically express what is obligatory, permitted, or forbidden in the system. When the s...
