AbstractThe past decade has seen large literatures develop around two novel invariants of directedgraphs: magnitude homology (due to Leinster, Hepworth and Wilerton) and the path homology ofGLMY theory. Though their origins are quite separate, Asao proved in 2022 that in fact thesehomology theories are intimately related. To every directed graph one can associate a certainspectral sequence - th...
AbstractFor over a decade, two theories have been actively developed: theory of magnitude and magnitude homology of metric spaces, and GLMY-theory of path homology of directed graphs. Recently Asao showed that for the case of directed graphs there is a unified approach to these theories via a spectral sequence which is now known as the magnitude-path spectral sequence. He also introduced a noti...
