Chain group math
WebFor any partiall ordered set ( S, ≤) a subset C ⊆ S is called a chain if C is totally ordered with respect to ≤. So the subgroups of G forming a chain means that the subgroups of G … WebFeb 9, 2024 · The group of such chains is denoted by Cn(X) C n ( X) and is called the n n th chain group of X X. In other words, Cn(X) C n ( X) is the free abelian group generated by the oriented n n -simplices in K K. We have defined chain groups for simplicial homology. Their definition is similar in singular homology and the homology of CW complexes.
