Canonical Representations on Lobachevsky Spaces: An Interaction with an Overalgebra

We define canonical representations R _λ , , for the Lobachevsky space ℒ=G/K of dimension n−1 where G=SO₀(n−1,1), K=SO(n−1), as the restriction to G of maximal degenerate series representations of the overgroup . We determine explicitly the interaction of Lie operators of with operators intertwining canonical representations and representations of G associated with a cone.
