In mathematics, homology is a general way of associating a sequence of algebraic objects, such as abelian groups or modules, with other mathematical objects such as topological spaces. Homology groups were originally defined in algebraic topology. Similar constructions are available in a wide … Meer weergeven Origins Homology theory can be said to start with the Euler polyhedron formula, or Euler characteristic. This was followed by Riemann's definition of genus and n-fold connectedness … Meer weergeven The homology of a topological space X is a set of topological invariants of X represented by its homology groups A one-dimensional sphere $${\displaystyle S^{1}}$$ Meer weergeven Homotopy groups are similar to homology groups in that they can represent "holes" in a topological space. There is a close connection between the first homotopy group $${\displaystyle \pi _{1}(X)}$$ and the first homology group $${\displaystyle H_{1}(X)}$$: … Meer weergeven Application in pure mathematics Notable theorems proved using homology include the following: • Meer weergeven The following text describes a general algorithm for constructing the homology groups. It may be easier for the reader to look at some simple examples first: graph homology and simplicial homology.
