We develop a formalization of the Size-Change Principle in Isabelle/HOL and use it to construct formally certified termination proofs for recursive functions automatically.
We describe here a formal proof in the Coq system of the structure theorem for subresultants, which allows to prove formally the correctness of our implementation of the subresulta...
: The main thesis of this paper is that in order to use Description Logics in practical applications, a seamless integration with object-oriented system development methodologies m...
