The odd-prime localization conjecture for symplectic annular Khovanov homology

Let LL be a pp-periodic link for an odd prime pp, and let L\overline{L} be its quotient link, treated as an annular link with the axis of symmetry as the annular axis. Write H(BZp;Fp)=Fp[α,θ]/(α2)H^*(B\mathbb Z_p;\mathbb F_p)=\mathbb F_p[\alpha,\theta]/(\alpha^2), where deg(α)=1\deg(\alpha)=1 and deg(θ)=2\deg(\theta)=2, and let θ1H(BZp;Fp)\theta^{-1}H^*(B\mathbb Z_p;\mathbb F_p) denote the corresponding localization. The odd-prime localization conjecture. There is a spectral sequence with E1E_1 page isomorphic to

Khsymp(L;Fp)θ1H(BZp;Fp)\operatorname{Kh}_{symp}(L;\mathbb F_p)\otimes \theta^{-1}H^*(B\mathbb Z_p;\mathbb F_p)

and EE_\infty page isomorphic to

AKhsymp(L;Fp)θ1H(BZp;Fp).\operatorname{AKh}_{symp}(\overline{L};\mathbb F_p)\otimes \theta^{-1}H^*(B\mathbb Z_p;\mathbb F_p).

This would extend the established 2-periodic localization result to odd prime-periodic links. It is motivated by expected fixed-point localization for Lagrangian Floer cohomology with a Z/pZ\mathbb Z/p\mathbb Z-action, but such a theorem is not presently available in the paper's setting.
