Magnitude: a bibliography


This is a list of all the publications on magnitude of which I am aware. Here I mean "magnitude" in the specific sense of these papers.

The criterion for inclusion is that the paper is specifically about magnitude, or magnitude plays a major role in the work, rather than it merely including a citation.

I have included papers on magnitude of categories, which is usually called Euler characteristic. However, I have not included papers on the diversity measures that are closely related to magnitude, except for those in which magnitude is discussed explicitly.

You may also be interested in the list compiled by Mark Meckes of n-Category Café blog posts on magnitude, diversity, and closely related ideas.

Within each topic, papers are ordered by arXiv date. I'll add journal publication details as I learn them, and would be happy to hear of any I've missed.
