WebNov 3, 2024 · On a globally hyperbolic spacetime M the Klein-Gordon equation has unique advanced and retarded Green functions, ΔR ∈ 𝒟′ (M × M) and ΔA ∈ 𝒟′ (M × M) respectively. The advanced and retarded Green functions are … The equation was named after the physicists Oskar Klein and Walter Gordon, who in 1926 proposed that it describes relativistic electrons. Vladimir Fock also discovered the equation independently in 1926 slightly after Klein's work, in that Klein's paper was received on 28 April 1926, Fock's paper was received on 30 July 1926 and Gordon's paper on 29 September 1926. Other authors making similar claims in that same year Johann Kudar, Théophile de Donder and F…
