Abstract

What we describe as Poincaré’s method for computing the fundamental group was given by Poincaré 1895 only in terms of a few special examples. These examples were mainly 3-dimensional manifolds obtained from a solid cube by identifying its faces in various ways. However, they clearly exposed the fact that one finds generators from the 1-dimensional cells of the complex, and relations from the 2-dimensional cells. Let us take Poincaré’s example of the cube in which each face is identified with its opposite by translation (Figure 152).
