Blockwise Simplification of the Kerr-Newman Black Hole's Thermodynamical
State Space Ruppeiner Geometry    [PDF]

Edward Anderson

A coordinate system that blockwise-simplifies the Kerr--Newman black hole's thermodynamical state space Ruppeiner metric is constructed, with discussion of the limiting cases corresponding to simpler black holes. It is deduced that one of the three conformal Killing vectors of the Reissner--Nordstr\"{o}m and Kerr cases (whose thermodynamical state space metrics are 2 by 2 and, moreover, conformally flat) survives generalization to the Kerr--Newman case's 3 by 3 thermodynamical state space metric.
