IntroductionThis course is devoted to the notion of magnitude homology and its relation to Euler characteristic of a finite category and GLMY-theory for digraphs. Tom Leinster in 2006 introduced a notion of Euler characteristic of a finite category, which is a rational number (not necessarily integer) that coincides with the Euler characteristic of the classifying space, when it is defined. Lat...
