Abstract:
We consider the pointed Lobachevsky space $\Lambda$. In terms of the Beltrami–Klein model, we obtain an explicit expression for the action of the multiplicative group of nonzero real numbers on the space $\Lambda$. This action is analogous to that of this group on the pointed Euclidean space.
Keywords:Lobachevsky space, Beltrami–Klein model, multiplicative group of nonzero real numbers.
