Perlick, Volker Editorial note to: “On the transition from wave optics to geometric optics in general relativity” by Jürgen Ehlers. (English) Zbl 1490.83008 Gen. Relativ. Gravitation 54, No. 4, Paper No. 39, 5 p. (2022). From the text: The paper [Gen. Relativ. Gravitation 54, No. 4, Paper No. 40, 9 p. (2022; Zbl 1490.83006)] by J. Ehlers that we revisit here was the first publication where this approximation was rigorously worked out on an arbitrary general-relativistic spacetime.
