This paper presents a machine-checked proof of the Basic Theorem on Concept Lattices, which appears in the book “Formal Concept Analysis” by Ganter and Wille, in the Isabelle/H...
We developed an importer from both HOL 4 and HOL-light into Isabelle/HOL. The importer works by replaying proofs within Isabelle/HOL that have been recorded in HOL 4 or HOL-light a...
Abstract. This paper presents a formalization of nite and in nite sequences in domain theory carried out in the theorem prover Isabelle. The results are used to model the metatheor...
We describe a formalization of the elementary algebra, topology and analysis of finite-dimensional Euclidean space in the HOL Light theorem prover. (Euclidean space is RN with the...
Induction proofs often fail because the stated theorem is noninductive, in which case the user must strengthen the theorem or prove auxiliary properties before performing the induc...
