Scaling and conformal symmetries for plane gravitational waves
P. -M. Zhang, M. Cariglia, M. Elbistan +1
The isometries of an exact plane gravitational wave are symmetries for both massive and massless particles. Their conformal extensions are in fact chrono-projective transformations…

"Kepler Harmonies" and conformal symmetries
P. -M. Zhang, M. Cariglia, M. Elbistan +2
Kepler's rescaling becomes, when "Eisenhart-Duval lifted" to -dimensional "Bargmann" gravitational wave spacetime, an ordinary spacetime symmetry for motion along null geodesics…
