\(H\)-SPACES (\(H_{41}\), \(g\)) OF TYPE {41}: PROJECTIVE-GROUP PROPERTIES

Aminova A.V., Khakimov D.R.

In this paper we study five-dimensional \(h\)-spaces (\(H_{41}\), \(g\)) of type {41} [4]. Necessary and sufficient conditions for (\(H_{41}\), \(g\)) to be a space of constant curvature are found. The general solution of the Eisnhart equation in \(h\)-space (\(H_{41}\), \(g\)) of non-constant curvature is determined. We establish conditions for the existence of a non-homothetic projective motion in (\(H_{41}\), \(g\)) and describe the structure of a non-homothetic projective Lie algebra in \(h\)-space (\(H_{41}\), \(g\)) of type {41}.

Keywords: five-dimensional pseudo-Riemannian manifold, \(h\)-space of type {41}, Eisenhart equation, projective Lie algebra.
