For persistent homology, we use coefficients in a field. So simplicial k-chains are vectors and the set of simplicial k-chains is a vector space. Furthermore, the boundary map is a linear transformation. For finite simplices, it is represented by a matrix. circumstantial relationship

"WebbYou could try John Lee's book Topological Manifolds, Ch 13 for singular homology (some definitions are in Ch 5). Then his book Smooth Manifolds, Chs 17 and 18 pick up where the previous book leaves off, and cover De Rham cohomology and its relation to singular homology. Obviously you'll need to be familiar with topology and smooth manifolds. " - Simplicial homology python
