simplicial complex topology
This setup does not require the definition of a metric and then it is especially useful to deal with signals defined over non-metric spaces. The simplicial homology groups and their corresponding Betti numbers are topological invariants that characterize the -dimensional "holes" in the complex. This is a simplicial complex with simplices of dimension 0, 1, and 2, such that its reduced homology is isomorphic to Z / qZ in dimension 1, zero otherwise. Simplicial Topology In this chapter a topological space X(or space, for short) is a subset of some Euclidean space Rd, endowed with the induced topology of Rd. It is represented in Sage by the tuple of the vertices. This means a subset of the complex is closed if and only if its intersection with each simplex is closed. Simplicial Complexes Singular homology is de ned for arbitrary spaces, but as we have seen it may be quite hard to calculate. Thus, we can consider more traditional metrics as adopting a “simplicial approach,” while a “topological approach” focuses on topological features associated with sequences of simplicial complexes.
