We describe a novel method for verifying programs that manipulate linked lists, based on two new predicates that characterize reachability of heap cells. These predicates allow re...
Causation is defined recursively: event e is the cause of condition φ in context c iff e is the only sufficient cause of φ in c, and removing e from c either removes φ from c...
abstract. We investigate an alternative presentation of classical and positive modal logic where the coalgebraic cover modality is taken as primitive. For each logic, we present a ...
