,Fundamental Groupoid and van Kampen’s Theorem,paces or the space arises as a gluing of subspaces right away. Our first goal is to find means that in both cases allow to compute the fundamental group of the space in terms of the fundamental groups of its constituents. We should keep in mind, however, that the fundamental group .(., .) of a topol

Homology: Ideas and Axioms,verall idea of homology as an alternative and more accessible topological tool. We begin with the introduction of ., a variant of homology that is only defined for a special type of spaces but for which the original, combinatorial idea still shines through. The basic properties of simplicial homolog

To make this program work for a general topological space ., it seems that the only chance to come up with a functorial construction—involving no choices—is to audaciously consider all possible
