“…If the orbit Ω(π) is saturated with respect to g , then γ(Ω(π)) is the union of a one parameter family ω t (t ∈ R) of G -orbits. It follows from [3] that π |K is of finite multiplicities, if and only if π t |K is of finite multiplicities for almost all t ∈ R and the orbit K • l is saturated with respect to g for µ π -almost all l ∈ Ω(π). By the induction hypothesis we know that for every t ∈ R such that π t|K is of finite multiplicities, the subspaces b[l t|k ] + g (l t ) are lagrangian for B l t at µ π t -almost all l t ∈ ω t .…”

“…Then a l can be identified with a l . We know from [3], that U π (g) k ⊂ U(l q−1 ) + ker(π). Hence we can apply the induction hypothesis to π and a l .…”

“…In case g is a nilpotent Lie algebra, appreciable advances have been achieved in the last few years by Corwin-Greenleaf [10], FujiwaraLion-Magneron-Mehdi [14], Baklouti-Fujiwara [5] and Baklouti-Ludwig [6]. In case where G and H are reductive groups, F. Knop [18] gives a satisfying and remarkable answer to the conjecture.…”
