Predicate Transformer Semantics for Hybrid Systems: Verification Components for Isabelle/HOL
share
We present a semantic framework for the deductive verification of hybrid systems with Isabelle/HOL. It supports reasoning about the temporal evolutions of hybrid programs in the style of differential dynamic logic modelled by flows or invariant sets for vector fields. We introduce the semantic foundations of our approach and summarise their Isabelle formalisation as well as the resulting verification components. A series of examples shows our approach at work.
