摘要

We comment on the article by M. Ozdemir and M. Erdogdu [9]. We indicate that the exponential map onto the Lorentz group can be obtained in two elementary ways. The first way utilizes a commutative algebra involving a conjugate of a semi-skew-symmetric matrix, and the second way is based on the classical epimorphism from SL(2, C) onto SO0(3, 1).
