WebA practical algorithmic approach to the computation of fundamental groups and first homology groups (as finitely presented groups), of firsthomology groups mod p (as vector spaces), of deck groups ( as permutation groups), and of covers of finite simple such complexes. 26 View 1 excerpt, references background WebComputing the homology groups and Betti numbers of a hypergraph is an extensive process, and by no means can it efficiently be done by hand, especially in the case of very large hypergraphs. The general steps with definitions are outlined below: Figure 2. A typical schematic demonstrating the homotopy equivalence of a coffee mug and the torus.

WebHomology groups are similar to homotopy groups in that they can represent "holes" in a topological space. However, homotopy groups are often very complex and hard to compute. In contrast, homology groups are commutative (as are the higher homology groups). Hence, it is sometimes said that "homology is a commutative alternative to homotopy". [7] headaches raised icp
