Combining Isabelle and QEPCAD-B in the Prover's Palette

摘要

We present the Prover's Palette, a framework for combining mathematical tools, and describe an integration of the theorem prover Isabelle with the computer algebra system QEPCAD-B following this approach. Examples are used to show how results from QEPCAD can be used in a variety of ways, with and without trust. We include new functionality for instantiating witnesses automatically and auto-running where applicable. We conclude that user-centric design yields systems integrations which are extremely versatile and easy to use.
