On new realizations of the poincare groups <em class="a-plus-plus">P</em> (1,2) and <em class="a-plus-plus">P</em>(2, 2)

Abstract

We classify realizations of the Poincare groups P (1, 2) and P (2, 2) in the class of local Lie groups of transformations and obtain new realizations of the Lie algebras of infinitesimal operators of these groups.
