The complementary group of proper motions of the minkowski metricN.N. Popov (pp. 103-110)
Abstract.It is shown that the Poincare group which is a semidirect product of the group of translations and the Lorentz group, is not a single phisicaly important group of proper motions of Minkowski metric. The complementary group of proper motions of the metric in a class of noninertial reference system has been found.
Keywords:Poincare group, Lorentz group, Minkowski metric, proper motions of metric, pseudo- orthogonal transformation.
