The usual contraction of the Poincar to the Galilei group is seen to be equivalent to a certain coordinate transformation.3 p.application/pdfeng(c) American Institute of Physics, 1978Àlgebres de LieTeoria quàntica de campsDinàmicaLie algebrasQuantum field theoryDynamicsThe groups of Poincaré and Galilei in arbitrary dimensional spacesinfo:eu-repo/semantics/article10127info:eu-repo/semantics/openAccess
