The non-genericity classification conjecture for unramified metaplectic representations

Let G(r)G^{(r)} be an rr-fold metaplectic covering group, and let π\pi be the unramified representation of G(r)G^{(r)} defined in the preceding construction. Suppose that HH is contained in a Levi part of a parabolic subgroup of GG, and that GL1k×HGL_1^k\times H is a Levi part of a parabolic subgroup PP of GG. For an arbitrary unramified character μ\mu of GL1kGL_1^k, let ΘH(r)\Theta_H^{(r)} be the Theta representation of H(r)H^{(r)}, and consider

IndP(r)G(r)μΘH(r)δP1/2.\operatorname{Ind}_{P^{(r)}}^{G^{(r)}}\mu\Theta_H^{(r)}\delta_P^{1/2}.

Non-genericity classification conjecture. Ignoring the special cases mentioned in the paper, π\pi is not generic if and only if it is a subrepresentation of

IndP(r)G(r)μΘH(r)δP1/2\operatorname{Ind}_{P^{(r)}}^{G^{(r)}}\mu\Theta_H^{(r)}\delta_P^{1/2}

for some μ\mu and ΘH(r)\Theta_H^{(r)} such that ΘH(r)\Theta_H^{(r)} is not generic. This aims to characterize non-generic unramified representations through induction from non-generic Theta representations, while explicitly excluding the special cases treated separately in the paper.
