The refined Adams conjecture for ABV-packets

Less than 1 year old · traced to

Let G=G(Wn)G=G(W_n) and H±=H(Vm±)H^\pm=H(V_m^\pm) be members of the relevant classical dual-pair towers, and let ϕ∈Φ(G)\phi\in\Phi(G). Define ϕα\phi_\alpha by

ϕα=(χWχV−1⊗cϕ∨)⊕(⨁i=0α−1χW∣⋅∣α−12−i⊗S1).\phi_\alpha=(\chi_W\chi_V^{-1}\otimes{}^c\phi^\vee)\oplus\left(\bigoplus_{i=0}^{\alpha-1}\chi_W|\cdot|^{\frac{\alpha-1}{2}-i}\otimes S_1\right).

The refined Adams conjecture for ABV-packets. If π∈ΠϕABV\pi\in\Pi_\phi^{\mathrm{ABV}}, then: (1) for α≫0\alpha\gg0, θ−α±(π)∈ΠϕαABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{\phi_\alpha}^{\mathrm{ABV}}; (2) if θ−α+(π)≠0\theta_{-\alpha}^+(\pi)\neq0, then θ−α±(π)∈ΠϕαABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{\phi_\alpha}^{\mathrm{ABV}}; (3) if θ−α±(π)∈ΠϕαABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{\phi_\alpha}^{\mathrm{ABV}} for some α\alpha, then θ−(α+2)±(π)∈Πϕα+2ABV\theta_{-(\alpha+2)}^\pm(\pi)\in\Pi_{\phi_{\alpha+2}}^{\mathrm{ABV}}; (4) if θ−α±(π)∈ΠϕαABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{\phi_\alpha}^{\mathrm{ABV}}, then θ−α±(π)∈Π(ϕπ)αABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{(\phi_\pi)_\alpha}^{\mathrm{ABV}}; and (5), if π∈ΠϕABV∩Πϕ′ABV\pi\in\Pi_\phi^{\mathrm{ABV}}\cap\Pi_{\phi'}^{\mathrm{ABV}} with ϕ≥Cϕ′\phi\geq_C\phi', then θ−α±(π)∈Π(ϕ′)αABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{(\phi')_\alpha}^{\mathrm{ABV}} implies θ−α±(π)∈ΠϕαABV\theta_{-\alpha}^\pm(\pi)\in\Pi_{\phi_\alpha}^{\mathrm{ABV}}.
