Predicate Transformer Semantics for Hybrid Systems
Jonathan Julián Huerta y Munive, Georg Struth · Journal of Automated Reasoning · 2021
Abstract 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 this framework and summarise their Isabelle formalisation as well as the resulting verification components. A series of simple examples shows our approach at work.
