I found a book on the interesting and very difficult topic of many-body classical relativistic theory

Classical Relativistic Many-Body Dynamics

Trump, M.A., Schieve, W.C
Springer, Fundamental Theories of Physics, Vol. 103

This relativistic covariant many-body formulation overcomes the no go theorem by Jordan and Sudarshan [1] by giving up the locality of the interactions and the individual mass-shell conditions. These are not simply cosmetic upgrades but have serious consequences on how we should understand classical physics.

Geo-coordinates for citations on scientific papers

Here I draw a map for the places that either published a paper mentioning the word Bures measure or were referenced by somebody who used the word Bures measure

The corresponding plot with the citations as links was created by my brother Ruben Cabrera

The total number of papers in consideration were 662. The extraction of coordinates from heterogeneous references is an expensive computational task.
