Learning Lean Through Architecture | Volume 2: The Curry-Howard Correspondence

Lean is becoming a serious tool in modern mathematics as researchers and students use it to write proofs that a computer checks automatically. As curious newcomers begin to ask how this software actually works, they often find the answers buried in highly technical research papers. This book aims to make the mechanics of automated reasoning accessible to anyone who loves math but has never opened a textbook on formal logic. This second volume explains the Curry-Howard correspondence and how it is used to automatically verify proofs.
