Homology Theory and Abelianization,the computation of numerical invariants of a manifold by means of decomposition into “cells”; the computations involve only the numbers of cells and the incidence relations between them, and it is shown that certain numbers are independent of the particular cellular subdivision chosen.

Graphs and Free Groups,e of free groups in combinatorial group theory, as the most general groups from the point of view of generators and relations, his picture of them remained the function-theoretic one—a tessellation of the unit disc by curvilinear triangles whose sides were circular arcs orthogonal to the disc bounda

Foundations for the Fundamental Group, defined the group in function-theoretic terms by considering analytic continuation of a many-valued function Φ around a closed path . in a manifold. Since the value obtained after completing . may differ from the initial value, . may be considered to define a transformation of Φ, and since any path
