mardi 16 mai Markus Müller-Olm Logics for Asynchronous Hyperproperties Hybride
Logics for Hyperproperties have received increasing attention in the last decade due to their importance e.g. for security analyses. Past approaches have focussed on synchronous properties, i.e. techniques in which different paths are explored lockstepwise. More recently automata models and logics supporting also asynchronous hyperproperties have been studied. In this talk I will survey our recent research on logics for asynchronous hyperproperties. This is joint work with Jens Gutsfeld and Christoph Ohrem.
mardi 30 mai Sławek Lasota Orbit-finite linear programming Online
An infinite set is orbit-finite if, up to permutations of the underlying structure of atoms, it has only finitely many elements. We study a generalisation of linear programming where constraints are expressed by an orbit-finite system of linear inequalities over an orbit-finite set of unknowns. As our principal contribution we provide a decision procedure for checking if such a system has a real solution, and for computing the minimal/maximal value of a linear objective function over the solution set. We also show undecidability of these problems in case when only integer solutions are considered. Therefore orbit-finite linear programming is decidable, while orbit-finite integer linear programming is not.
