After the collapse, each connected component will have only one vertex with many loops on it, one loop for each edge of the connected component no in the spanning tree. …

WebFeb 15, 2005 · Our approach permits the extension to infinite graphs of standard results about finite graph homology – such as cycle–cocycle duality and Whitney's theorem, Tutte's generating theorem, MacLane's planarity criterion, the Tutte/Nash-Williams tree packing theorem – whose infinite versions would otherwise fail.

WebMay 29, 2024 · $\begingroup$ @saulspatz this is the usual meaning of "acyclic" in the context of homology theories, it is an unfortunate terminology collision in this case. (However, note that in terms of singular homology, a graph is graph-acyclic iff it is homology-acyclic) $\endgroup$ – greene county hospice ny
