Areas of the constant sign of curvatures of the left-invariant Riemannian metrics of three-dimensional Lie groups

In the given article on the language of structural constants of a three-dimensional Lie algebra sets of the left-invariant Riemannian metrics positive, non-negative, oscillating, that is receiving values of miscellaneous signs, two-dimensional sectional curvature, unidimensional sectional curvature and curvature the Ricci geometrically are described.
