Abstract:
In the present paper we construct a 10-dimensional group which induces
the Laguerre transformations of planes in the three-dimensional pseudo-
Euclidean space ${}^1E_3$, and find action of this group on the tangent bundle
of complex projective line, on the 4-dimensional pseudo-Euclidean space,
and on the manifold of horospheres of the ideal area of three-dimensional
Lobachevskii space.
