Homology basis
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 numerical invariants in 1857 and Betti's proof in 1871 of the independence of "homology numbers" from the choice of … Meer weergeven 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 … 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 $${\displaystyle S^{1}}$$ is a circle. It has a single connected component and a one-dimensional … Meer weergeven The different types of homology theory arise from functors mapping from various categories of mathematical objects to the category of … 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.
