Summary
In this paper the basic principles of Einstein’s, Schrödinger’s and Bonnor’s unified field theory have been studied. Originally the field equations were given in terms of contracted curvature tensor Rμλ Here the relations are obtained between Rμλ and some other tensors like Einstein’s tensor, transposed tensor and tne tensor T β[γα]α and the field equations are modified in terms of these tensors. Incidentally it has been shown how these tensors are obtained in a number of ways in Ricci identities when the covariant differentiations are performed taking into consideration the nature of the indices.
Riassunto
Si studiano nel présente lavoro i principi fondamentali della teoria del campo unificato di Einstein, Schrödinger e Bonnor. Originalmente le equazioni di campo erano date in termini del tensore di curvatura contratto Rμλ Qui si ottengono relazioni traR μλ e alcuni altri tensori, come il tensore di Einstein, il tensore trasporto e il tensoreT gaβ[γα] e si modificano le equazioni di campo in termini di tali tensori. Si mostra anche come questi tensori si ottengano in vari modi nelle identità di Kicci se si eseguono le derivazioni covarianti tenendo conto della natura degli indici.
