This paper introduces (one-path) reachability logic, a language-independent proof system
for program verification, which takes an operational semantics as axioms and derives …

This paper introduces matching logic, a novel framework for defining axiomatic semantics for
programming languages, inspired from operational semantics. Matching logic specifications …

This paper presents a verification framework that is parametric in a (trusted) operational
semantics of some programming language. The underlying proof system is language …

We propose a methodology based on testing as a framework to capture the interactions of a
machine represented in a denotational model and the data it manipulates. Using a …

It is not always clear what computer programs mean in the various languages in which they
can be written, yet a picture can be worth 1000 words, a diagram 1000 instructions. In this …

Hilbert and Ackermann asked for a method to consistently extend incomplete theories to
complete theories. Gödel essentially proved that any theory capable of encoding its own …

Geospatial data availability, interoperability, and integration remain a problem today.
Current spatial data infrastructures (SDIs) are of limited use particularly to non-expert user …

This paper presents an overview of the technical foundations and current directions of
Kestrel's approach to mechanizing software development. The approach emphasizes …

We advocate an automated refinement approach to develo** programs and their proofs.
The approach is partially embodied in the Specware system [6] which has found industrial …

Self-adaptive systems continuously adapt to internal and external changes in their execution
environment. In context-based self-adaptation, adaptations take place in response to the …
