Electromagnetic Tensor Field Of First And Second Class

Abstract

The author and R.S. Mishra established the identities in Nijenhuis tensor for first, second and third class of electromagnetic tensor fields. The identities for first class were non zero. In this paper I have obtained the identities which are zero for first class in tensor M(X,Y). The identities for the second class have also been obtained in M(X, Y) with respect to electromagnetic tensor field in four dimensional space-time.
