This chapter outlines the concepts and techniques that underlie reasoning in Isabelle. Until
now, we have proved everything using only induction and simplification, but any serious …

Abstract Development of formal proofs of correctness of programs can increase actual and
perceived reliability and facilitate better understanding of program specifications and their …

Heterogeneous specification becomes more and more important because complex systems
are often specified using multiple viewpoints, involving multiple formalisms (see Fig. 1) …

We introduce Jinja, a Java-like programming language with a formal semantics designed to
exhibit core features of the Java language architecture. Jinja is a compromise between the …

Hammers provide most powerful general purpose automation for proof assistants based on
HOL and set theory today. Despite the gaining popularity of the more advanced versions of …

Isabelle, which is available from http://isabelle. in. tum. de, is a generic framework for
interactive theorem proving. The Isabelle/Pure meta-logic allows the formalization of the …

The Isabelle system essentially provides a generic infrastructure for building deductive
systems (programmed in Standard ML), with a special focus on interactive theorem proving …

Semantic definitions of full-scale programming languages are rarely given, despite the many
potential benefits. Partly this is because the available metalanguages for expressing …

We present the first verification of full functional correctness for a range of linked data
structure implementations, including mutable lists, trees, graphs, and hash tables …
