Computing homology

WebOct 1, 2010 · A new approach to algorithmic computation of the homology of spaces and maps is presented, based on a combinatorial variant of the Čech homology and the Nerve Theorem that may help in bypassing the problems with the complexity of the standard homology algorithms by reducing the size of necessary input. A new approach to … WebTopological data analysis (TDA) is often considered as the way to characterize the shape of data. The way we do this is by taking a set of data points, computing its Cech complex across a range of resolutions, and recording how the homology groups change in what is called a persistence landscape.

Our approach is based on inverse … WebIntersection homology is a topological invariant which detects finer informa-tion in a space than ordinary homology. Using ideas from classical simple homotopy the-ory, we construct local combinatorial transformations on simplicial complexes under which intersection homology remains invariant. In particular, we obtain the notions of stratified
