“…To borrow a phrase of Obukhov and Solodukhin, the research has a dramatic history, see Graf [4], Benn and Tuchker [5,6], Budinich and Bugajska [7], Rabin [8], Bullinaria [9], Ivanenko and Obukhov [10], Obukhov and Solodukhin [11,12], Mankoč Borštnik and Nielsen [13]. In particular, substantial study on the connection to the Lattice fermion has been investigated by many scholars, see Becher and Joos [14], Rabin [8], Mitra [15], Bullinaria [16], Göckeler and Joos [17], Smalley [18].…”

In this paper, we illustrated one scenario to modify the Ivanenko-Landau-Kähler equation. Since Ivanenko and Landau introduced the equation in 1928, the equation has been regarded as having a certain role as a fermion in particular in the discrete Lattice. Also, although it correctly is formulated as an alternative classical field equation by the Ideal projection for the Dirac equation in the Minkowski space-time, so does it only in that flat geometry. I. M. Benn and R. W. Tucker in 1985 and Yu. N. Obukhov and S. N. Solodukhin in 1994 suggested two resolutions respectively. They modified the equation in order for it to make senses as an alternative for the Dirac equation in the general space-time. This paper advances a still another approach, however in the Minkowski space yet, as the first stage toward the generalization. Two ingredients for the modifications are essential. One is the restriction of the space of anti-symmetric tensor field to only its subalgebras, not to its Ideals.The other is the modification on the mass term for the equation to mean the eigenvalue problem generating physical states. The Vector U(1) and the Axial U(1) symmetries built in the modified equation are described.
