Program verification in the large is not only a matter of mechanizing a program logic to
handle the semantics of your programming language. You must reason in the mathematics …

This paper presents a simple mechanized formalization of Separation Logic for sequential
programs. This formalization is aimed for teaching the ideas of Separation Logic, including …

This article gives an in-depth presentation of the omni-big-step and omni-small-step styles of
semantic judgments. These styles describe operational semantics by relating starting states …

Today, a typical project in rigorous reasoning about programming languages begins with an
operational semantics (or maybe several), with proofs of key lemmas proceeding by …

Reasoning systems based on Concurrent Separation Logic make verifying complex
concurrent algorithms readily possible. Such algorithms contain subtle protocols of …
