I reira i te tahi mau tautooraa ki te tiki i te huringa Lorentz kahore te tāpaetanga o te pūmau o te tere o te marama. Vladimir Ignatowski (1910) hei tauira whakamahia hoki tenei whakaaro (he) te parau tumu o te pānga, (b) homogeneity me te isotropy o te wāhi, me te (c) te whakaritenga o te reciprocity. Philipp Frank ko Hermann Rothe (1911) tohe e he oti tenei tangohanga, me te hiahia tāpiritanga atu. hāngai ratou ake tātai i runga i te whakaaro e: (he) hanga i te huringa Lorentz he rōpū rārangi homogeneous, (b) ka huri i anga, anake te tohu o te huringa tere whanaunga, (c) whakapeka e tika ana anake i runga i te tere whanaunga. Heoi, kia rite ki Pauli ko Miller tauira ki te tautuhi i taua invariant i roto i to ratou tere ki te tere o te marama, hei tauira, i whakamahia (a) te parau tumu o te pānga, (b) homogeneity me te isotropy o te wāhi, me te (c) te whakaritenga o te reciproc
