In the process of interactive theorem proving one often works with incomplete higher order proofs. In this paper we address the problem of giving a correctness criterion for these ...
Abstract. We give the first mechanized proof of the fact that for showing termination of a term rewrite system, we may restrict to well-formed terms using just the function symbols...
Reactive integrated development environments for software engineering have lead to an increase in productivity and quality of programs produced. They have done so by replacing the...
Abstract. This paper provides an overview of Proof-Based System Engineering (PBSE), which aims at improving the current practice of developing computer-based systems. PBSE is of pa...
Development graphs are a tool for dealing with structured specifications in a formal program development in order to ease the management of change and reusing proofs. In this work...
