一句话:在同伦类型论中引入(半)2-伴随等价并证明其预期性质,且在 Lean 中形式化。
本文在同伦类型论(HoTT)框架下引入(半)2-伴随等价((half) 2-adjoint equivalences)这一高阶等价概念,旨在为同伦类型论中的高阶伴随结构提供类型论定义与性质刻画。作者证明该概念所应满足的一系列预期性质,从而推进对同伦类型论中等价理论的理解。所有结果均在 Lean 定理证明器中形式化,给出机器验证的保证。该工作的问题在于如何在同伦类型论中定义并处理(半)2-伴随等价;方法是在 HoTT 中引入定义并证明其性质;评估方式为 Lean 形式化验证。
We introduce the notion of (half) 2-adjoint equivalences in Homotopy Type Theory and prove their expected properties. We formalized these results in the Lean Theorem Prover.
