Abstract

It is shown that to each finite‐dimensional single‐valued irreducible representation of SL(3, R) there corresponds an infinite‐dimensional representation which is unitary on any member of a certain one‐parameter family of Hilbert spaces. We set up an eigenfunction problem for the members of a three‐parameter family of Hilbert subspaces on which such a unitary representation is irreducible. The relatively simple but especially important three‐dimensional case is worked out completely. Unitary irreducible representations for the unimodular real linear groups SL(N, R) with N > 3 and their subgroups can be obtained by generalizing the formalism described here.
