%X Necessary and sufficient conditions for the existence of the group inverse of the block matrix <img src=\"Edit_39337c9c-bdbd-4cc0-a419-133a89460ff1.bmp\" alt=\"\" /> in Minkowski Space are studied, where <img src=\"Edit_97121fd1-15cc-4494-9f30-5d4e9b4e357a.bmp\" alt=\"\" /> are both square and <img src=\"Edit_2c3c074c-cee8-4796-a713-c36baaadbbcb.bmp\" alt=\"\" />. The representation of this group inverse and some related additive results are also given.
