Perrin-Riou–Bernardi supersingular p-adic Birch–Swinnerton-Dyer conjecture

About 1 year old · traced to

Let EE be an elliptic curve over Q\mathbb{Q} with good supersingular reduction at pp, and let r=rank⁡E(Q)r=\operatorname{rank}E(\mathbb{Q}). Let Lp(E,T)L_p(E,T) be the supersingular pp-adic LL-series, let Lp∗(E,0)L_p^*(E,0) denote its leading term at T=0T=0, let ϕ\phi be Frobenius on the Dieudonné module DpED_pE, and let Reg⁡p(E/Q)\operatorname{Reg}_p(E/\mathbb{Q}) be the pp-adic regulator. Perrin-Riou–Bernardi's conjecture. The order of vanishing of Lp(E,T)L_p(E,T) at T=0T=0 is rr, and

(1−ϕ)−2Lp∗(E,0)=∏vcv⋅Sha⁡(E/Q)∣E(Q)tors∣2⋅Reg⁡p(E/Q)pr.(1-\phi)^{-2}L_p^*(E,0)=\frac{\prod_v c_v\cdot\operatorname{Sha}(E/\mathbb{Q})}{|E(\mathbb{Q})_{\mathrm{tors}}|^2}\cdot\frac{\operatorname{Reg}_p(E/\mathbb{Q})}{p^r}.

This is the supersingular pp-adic analogue of the Birch–Swinnerton-Dyer conjecture, relating the analytic leading term to Tamagawa factors, the Tate–Shafarevich group, torsion, and the pp-adic regulator. The supplied text gives no resolution status.
