## Classification of real structures of Lie algebras of fifth order.(Russian)Zbl 0166.04201

The author gives the classification of five-dimensional real Lie algebras. It is shown that there exists a unique real nonsolvable five-dimensional Lie algebra of the structure $$g_5$$: $e_1\circ e_2=2e_4,\;e_4\circ e_3=-e_2,\;e_2\circ e_3=2e_3,\;e_1\circ e_4=e_5,\;e_2\circ e_4=e_4,\;e_2\circ e_5=-e_5,\;e_3\circ e_5=e_4.$
