About this paper
Zhaoxi Chen, Daniel Raggi
The authors present a Lean tactic family that translates proofs between different representations by composing tagged transfer rules, including rules for functions and types that differ. In tests ported from Mathlib’s gcongr and grw suites, transfer closes 112 of 178 cases; 54 are interface deferrals and 12 partial-progress deferrals. Dependency comparisons show no crossover against established library proofs.
