ABSTRACT
Specification languages have long featured ways to describe what does not change when an imperative procedure is executed: the so-called frame problem. Solutions to the frame problem are needed for formal verification in imperative programming, as otherwise a verification would not be able to accumulate information from one statement to the next. Region logic is one of the approaches to solving the frame problem. We present a modified version of region logic with fine granularity and introduce conditional effects that allows one to specify more precise frame conditions.

Unifying separation logic and region logic to allow interoperability
AbstractFraming is important for specification and verification, especially in programs that mutate data structures with shared data, such as DAGs. Both separation logic and region logic are successful approaches to framing, with separation logic ...
Substructural logic and partial correctness
We formulate a noncommutative sequent calculus for partial correctness that subsumes propositional Hoare Logic. Partial correctness assertions are represented by intuitionistic linear implication. We prove soundness and completeness over relational and ...
Extending hoare logic to real-time
AbstractClassical Hoare triples are modified to specify and design distributed real-time systems. The assertion language is extended with primitives to express the timing of observable actions. Further the interpretation of triples is adapted such that ...
