We describe formalization of the Poincaré disc model of hyperbolic geometry within the Isabelle/HOL proof assistant. The model is defined within the complex projective line CP^ 1 …
In this thesis, we investigate how a proof assistant can be used to study the foundations of geometry. We start by focusing on ways to axiomatize Euclidean geometry and their …

A constructive nonstandard interpretation of a multiscale affine transformation scheme is presented. It is based on the Ω Ω-numbers of Laugwitz and Schmieden and on the discrete …

We propose a generic approach to make arithmetic decision procedures designed for the concrete data-type Z of Coq available for alternative representations of integers. It is based …

The paper describes three models of the real field based on subsets of the integer sequences. The three models are compared to the Harthong–Reeb line. Two of the new …
In this thesis we will integrate concepts of non-standard analysis into projective geometry. Especially, we will analyze the properties of a projective space over a non-Archimedean …
L'utilisation des assistants de preuve comme Coq prend de plus en plus d'ampleur. De tels outils permettent de démontrer formellement aussi bien des résultats mathématiques que …
In TYPES 2011, we presented a formal description of the Harthong-Reeb line based on axiomatic non-standard integers (intuitively they correspond to Z where we introduce a-new …
