title = "Ordinals in HOL: Transfinite arithmetic up to (and beyond) ω1",
abstract = "We describe a comprehensive HOL mechanisation of the theory of ordinal numbers, focusing on the basic arithmetic operations. Mechanised results include the existence of fixpoints such as ε 0, the existence of normal forms, and the validation of algorithms used in the ACL2 theorem-proving system.",
