An Implementation of Homotopy Type Theory in Isabelle/Pure (1911.00399v1)
Published 31 Oct 2019 in cs.LO and math.LO
Abstract: In this Masters thesis we present an implementation of a fragment of "book HoTT" as an object logic for the interactive proof assistant Isabelle. We also give a mathematical description of the underlying theory of the Isabelle/Pure logical framework, and discuss various issues and design decisions that arise when attempting to encode intensional dependent type theory with universes inside a simple type-theoretic logical foundation.
