Mazur–Tate–Teitelbaum p-adic BSD conjecture for elliptic curves

About 14 years old · traced to

Let E/QE/\mathbb{Q} be an elliptic curve with analytic rank ran(E/Q)=1r_{\mathrm{an}}(E/\mathbb{Q})=1. Let Lp,α(t)\mathcal{L}_{p,\alpha}(t) be the α\alpha-adic pp-adic LL-function, let α\alpha be the unit root, and let ⟨⋅,⋅⟩p,α,L\langle\cdot,\cdot\rangle_{p,\alpha,L} be the associated pp-adic height pairing. Let PP generate E(Q)/torsE(\mathbb{Q})_{/\mathrm{tors}}, and let χcyc\chi_{\mathrm{cyc}} be the pp-adic cyclotomic character.

Mazur–Tate–Teitelbaum's p-adic BSD conjecture. One should have

Lp,α′(0)=1log⁡p(χcyc(γ))(1−1α)2#\Sha(E/Q)⋅Tam⁡(E/Q)⋅⟨P,P⟩p,α,L(#E(Q)tors)2.\mathcal{L}_{p,\alpha}^{\prime}(0)=\frac{1}{\log_p(\chi_{\mathrm{cyc}}(\gamma))}\left(1-\frac{1}{\alpha}\right)^2\frac{\#\Sha(E/\mathbb{Q})\cdot\operatorname{Tam}(E/\mathbb{Q})\cdot\langle P,P\rangle_{p,\alpha,L}}{(\#E(\mathbb{Q})_{\mathrm{tors}})^2}.

The paper uses this conjecture in its pp-part under hypotheses from its main theorem; the full asserted equality is presented as a conjectural pp-adic analogue of BSD.
