โœฆ Synopsis


The classical "computation" methods in Algebraic Topology most often work by means of highly infinite objects and in fact are not constructive. Typical examples are shown to describe the nature of the problem. The Rubio-Sergeraert solution for Constructive Algebraic Topology is recalled. This is not only a theoretical solution: the concrete computer program Kenzo has been written down which precisely follows this method. This program has been used in various cases, opening new research subjects and producing in several cases significant results unreachable by hand. In particular the Kenzo program can compute the first homotopy groups of a simply connected arbitrary simplicial set.

The notion of elementary diameter is introduced to provide, in the context of Locale Theory, a constructive notion of metrisability. Besides foundational aspects, elementary diameters allow to express metrisability in locales more simply with respect to the existing (non-constructive) approach based

We describe a framework of algebraic structures in the proof assistant Coq. We have developed this framework as part of the FTA project in Nijmegen, in which a constructive proof of the fundamental theorem of algebra has been formalized in Coq. The algebraic hierarchy that is described here is both

The theory of apartness spaces, and their relation to topological spaces (in the point-set case) and uniform spaces (in the set-set case), is sketched. New notions of local decomposability and regularity are investigated, and the latter is used to produce an example of a classically metrisable apart
