4 x 4 matrices in Dirac parametrization: inversion problem and determinant

V. M. Red'kov, A. A. Bogush, N. G. Tokarevskaya

Parametrization of complex 4 x 4 - matrices G in terms of Dirac tensor parameters (A,B,A_{l},B_{l},F_{kl}) or equivalent four complex 4-vectors (k,m,n,l) is investigated. In the gi…
