Summary
It is shown that Schwinger’s formula for [T 00(x),T 00(y)] cannot be generalized, in a covariant fashion, to the other components of the energy-momentum tensor.
Riassunto
Si dimostra che la formula di Schwinger per [T 00(x),T 00(y)] non può essere genelizzata in modo covariante alle altre componenti del tensore energia-impulso.
