Interactive Proof Presentations with Cobra

Abstract

We present Cobra, a modern proof presentation framework, leveraging cutting-edge presentation technology together with a state of the art interactive theorem prover to present formalized mathematics as active documents. Cobra provides both an easy way to present proofs and a novel approach to auditorium interaction. The presentation is checked live by the theorem prover, and moreover allows for live changes both by the presenter and the audience.Comment: In Proceedings UITP 2016, arXiv:1701.0674
